- Department: Engineering
THIS POSITION IS NOW FILLED
Applications are invited for a fully funded PhD studentship (3.5 years) in the Faculty of Engineering at the University of Nottingham. The aim of the research is to investigate the relationships between dielectric spectroscopy and mechanical properties of polymers. Dielectric measurements enable probing of polymer behaviour at very high frequencies, which should offer new insight into the mechanical properties of polymers at impact conditions of high strain rates. The successful applicant will work collaboratively with a team of researchers at the University of Nottingham and the University of Oxford currently supported by the Dutch Polymer Institute, where work is on-going on the measurement and modelling of high strain rate properties of polymers, as well as with major collaborating polymer companies, and is expected to engage with further international collaborations. The student will work under the supervision of Dr Davide De Focatiis, on the development of techniques and theories for relating dielectric measurements and mechanical measurements, making use of existing experiments and guiding future efforts. By understanding some of the structure-property relationships, feedback can be provided towards constitutive modelling development and to the development of materials more tailored to specific high strain rate response.
Requirements of the studentship:
Students should have, or expect to obtain, a first-class degree, or a distinction at MSc level in materials engineering, mechanical engineering or a closely related discipline (a high 2:1 or high merit will be considered).

PhD Research Studentship 2012
Solid-state Properties of Processed Branched Polymers
- Reference: ENG584
- Closing Date: Friday, 27th April 2012
Applications are invited for a fully funded PhD studentship (3 years) in the Research Division of Materials, Mechanics and Structures in the Faculty of Engineering at the University of Nottingham.

The successful applicant will contribute to an EPSRC funded project within the Polymer Engineering group at the University of Nottingham, and in collaboration with other researchers in Nottingham, the UK and abroad. The student will work under the supervision of Dr Davide De Focatiis and in collaboration with senior researchers on the development of experimental techniques and of a constitutive model.
Requirements of the studentship:
- Students should have, or expect to obtain, a first-class or good 2:1 honours degree, or a distinction or high merit at MSc level in materials engineering, mechanical engineering, physics, applied mathematics or a closely related discipline.

Summer studentship 2011
Medical polymers for degradable implants: linear and non-linear creep

Crazes in a degraded PLA polymer
Degradable polymer implants have enormous potential in aiding the healing and recovery of injuries such as bone fractures in a carefully controlled way, and to avoid the need for the removal of metal implants after healing. In low risk applications there are already a number of polymer implants on the market. The Composites group at Nottingham has been working for some time to extend this to more demanding applications, where an understanding of the properties of the polymer during the degradation process becomes crucial. Over the past two summers, ERP students have researched into two main topics: the kinetics of craze initiation in degrading polymers, and the simultaneous evolution of crystallisation and degradation. The work so far has been very successful, and has led to a conference paper and to a journal article in preparation. The research can now attempt to move on to the measurement and prediction of the creep response of degrading polymers. This project will involve the manufacture and controlled degradation of poly(lactic acid) specimens, followed by a number of creep experiments performed in water at body temperature. The design of the experiments and protocol is crucial in maximising the amount of useful information, and in extracting material parameters suitable for possible modelling.
This project would ideally suit an MEng student in either Mechanical Engineering, Chemical Engineering or Environmental Engineering, although other students can be considered. No special qualifications required though some understanding of polymeric materials and materials characterisation would be an advantage. Training in the use of the equipment will be provided. Supervisors: Dr Davide De Focatiis and Dr Andy Parsons.
Summer studentship 2011
A resistivity text fixture for nanocomposite characterisation

The schematics of a resistivity test fixture
Our research group is investigating ways of making polymers electrically conductive by the addition of conductive nanoparticles such as carbon nanotubes. The properties of these nanocomposites depend not only on the nanotube content, but also on the processing history (since this has a significant effect on nanotube dispersion). Currently we are able to produce carbon nanotube nanocomposites based on polycarbonate and on thermoplastic polyurethane (an elastomer). In order to determine the electrical properties of these nanocomposites, we need to build a resistivity test fixture. Electrical resistivity is a geometry-independent measure of the ability of a material to resist the flow of electrical current. The fixture should ideally be able to measure both surface and volume resistivity, interfacing with our dedicated electrometer. The project will involve the design, construction and validation of a resistivity test fixture. The design of the fixture has to ensure a repeatable contact between electrodes and material, and appropriate shielding from electrical interference. The contact between the electrodes and the material will be facilitated by a conductive elastomer.
This project would ideally suit an MEng student in Mechanical Engineering, with good design skills and some ability to manufacture parts, although other students can be considered (eg. from Electrical Engineering or Chemical Engineering). No special qualifications required though an interest in materials science would be an advantage. Training in the use of the equipment and in electrical characterisation of materials will be provided. Supervisors: Dr Davide De Focatiis and Gabriel Choong.
Summer studentship 2011
Characterisation of a new polymer

A dendrimer and a hyperbranched polymer
Dr Derek Irvine’s research group has recently developed a novel technique to produce small quantities of a totally new polymer: poly(divinyl benzene). This polymer is structurally very similar to ordinary polystyrene, which consists of a carbon backbone chain with one benzene ring every two carbon atoms. Poly(divinyl benzene) has two benzene rings on opposite sides of the molecule every two carbon atoms. At the moment very little is known about the properties of this polymer; although it is expected to be broadly similar to polystyrene, it may result in a range of interesting properties and applications. The synthesis technique produces a resulting polymer with a high degree of chain branching, known as hyperbranched. The technique also allows for the production of random copolymers of styrene and divinyl benzene. This project will involve the production and characterisation of small quantities of poly(divinyl benzene) and copolymers with polystyrene. Synthesis will take place in the Chemistry department, and characterisation will involve analytical measurements of molecular weight, glass transition temperature and simple mechanical properties.
This project would ideally suit an MEng student in Chemical Engineering or Environmental Engineering, with good laboratory skills and the ability to think critically. An interest in polymers and/or chemistry would be an advantage. Training in the use of the analytical equipment will be provided. Supervisors: Dr Derek Irvine and Dr Davide De Focatiis.
Summer studentship 2010
Medical polymers for degradable implants: a study of the structure and properties during degradation

Crazes in a degraded PLA polymer
Degradable polymer implants have enormous potential in aiding the healing and recovery of injuries such as bone fractures in a carefully controlled way, and to avoid the need for the removal of metal implants after healing. In low risk applications there are already a number of polymer implants on the market. The Composites group at Nottingham has been working for some time to extend this to more demanding applications, where an understanding of the properties of the degrading polymer becomes crucial. Two particular characteristics of the polymer impact on the material performance as it degrades – the degree of crystallinity (i.e. how much of the polymer is crystalline and how much is amorphous), and the molecular weight (the length of the polymer chains, which reduces during degradation). Both of these properties affect the rate at which the polymer degrades and its mechanical properties: an understanding of the variation of these properties with time is needed in predicting the lifetime performance of such an implant. However, these characteristics are not independent – shorter polymer chains will crystallise more easily and crystallised polymer will not break down as fast as amorphous polymer. The aim of this project is to devise a careful series of experiments designed to explore the coupling of these two characteristics, in order to assist the design of models to describe the evolution of the polymer structure and properties over time. This will require careful analytical thought, meticulous sample preparation, and training in the use of cutting-edge analysis equipment in the engineering and chemistry departments.
This project would ideally suit an MEng student in either Chemical Engineering, Environmental Engineering or Mechanical Engineering, although other students can be considered. No special qualifications required though some understanding of polymeric materials and materials characterisation would be an advantage. Training in the use of analytical equipment will be provided. Supervisors: Dr Davide De Focatiis and Dr Andy Parsons.
Hyperbranched polymers: a study connecting their structure to properties and suitable applications

A dendrimer and a hyperbranched polymer
Dendritic, or hyperbranched polymers are unusual high molecular weight polymers in that they possess an extensive three-dimensional molecular structure, characterised by a large number of branching points and thus a very high density of end-groups and functional groups. In lay terms their shapes can be compared to a tree with many branches and sub-branches. These materials are manufactured via two key synthetic strategies (a) sequential growth of the molecule in layers to produce well-defined polymers called dendrimers and (b) the co-polymerisation of mono- and di-functional monomers to produce hyperbranched polymers. Hyperbranched polymers are less structurally well-defined, but considerably easier to manufacture in a single process stage. Dendritic polymers have unique properties because their many branches impart a globular shape and lead to exceptionally high end-functional group density. The unique three-dimensional structure of these materials has inspired a high degree of interest in the material science and engineering communities. These materials have been linked with numerous potential advances in applications reported, ranging from improved polymer processing, through to improved drug delivery systems, to their use as nano-building blocks for more complex structures. Unfortunately, characterisation and application has thus far been limited due to the inherent difficulties with the synthesis. Dendrimers are only accessible through the tedious, solvent-intensive, multi-step synthetic pathways. Recent work within the University of Nottingham has lead to a practical system to produce hyperbranched polymers in significant quantities within a couple of hours. This research involves carrying out a careful series of experiments designed to characterise the structure and the processability and mechanical properties of samples of these novel hyperbranched polymers. The aims of the project are to obtain high-quality experimental data that can assist in the design of models to describe the properties of these materials. Since most of these materials are novel, the student will have to carefully design possible processing strategies in order to perform the characterisation. This will require meticulous sample preparation, training in the use of cutting-edge analysis equipment in the engineering and chemistry departments, and dedication and insight to overcome challenging experimental problems. By the end of the project the student should be in a position to propose possible applications for the hyperbranced polymers produced using the Nottingham reactor. The student will be supervised by Dr Derek Irvine, Associate Professor in Chemical and Environmental Engineering and member of the Process and Environmental Research Division, and Dr Davide De Focatiis, Lecturer in Polymer Engineering and member of the Materials, Mechanics and Structures Research Division.
Summer studentship 2009
Investigating the effects of stress on creep failure of a biodegradable PLA polymer for medical applications (now appointed)

SEM of a degrading composite
PLA (polylactic acid) is a biodegradable thermoplastic polymer, an ideal candidate for the matrix material of a fully biodegradable phosphate glass fibre composite being developed in Nottingham with applications as synthetic bone substitutes and fracture fixation devices. The degradation and failure of the PLA matrix plays a key part in determining the degradation and failure of the composite. This project will investigate experimentally how the presence of stress enhances the speed of mechanical failure in the PLA matrix through a series of 3-point bending creep and tensile experiments on dry and wet PLA, at room and body temperatures. Specimens will be compression moulded directly to shape, and tested using an existing 3-point bending creep rig, and tensile testing equipment. The failure surfaces will be investigated further using microscopy in order to shed light on the mode of failure in the material. A commercial PLA grade will be used for the bulk of the experiments, followed if time permits by a limited number of miniature tests on a more precious medical grade PLA. If time permits, a limited number of tests on the composites will also be performed.
This project would ideally suit an MEng student in Mechanical Engineering, although other students can be considered. It is funded by the Mechanics, Materials and Structures and the Process and Environmental research divisions, at a rate of £180/week and will last for 8 weeks. Key deliverables are specimen production, mechanical tests and a brief report. Training will be provided where needed.
Summer studentship 2009
Investigating the changes in resistance with large deformation in a range of carbon nanotube – thermoplastic elastomer composites for wearable deformation sensors (now appointed)

A carbon nanotube
Carbon nanotubes (CNTs) provide a novel way to decrease the electrical resistance of polymers through the production of nanocomposites. When CNTs are mixed with elastomeric materials, large deformations of the composites are still possible. The resistance of the elastomeric composites changes with deformation both due to the shape change and due to the microstructural changes in the composite. It is intended to use these materials as large strain sensors with applications in areas such as medical rehabilitation, gait analysis, sports monitoring and motion capture. The project will investigate experimentally the changes in resistance with deformation in a small range of CNT-thermoplastic elastomer composites. Controlled deformations will be applied using standard tensile testing machines while monitoring the changes in resistance. Some manufacture of the test specimens by compression moulding and some development of the testing equipment and technique will be necessary. The aim is to help to produce a proof-of-concept sensor, and to shed light on what materials are suitable candidates for these sensors. This project forms part of a multidisciplinary collaboration through a Bridging the Gaps scheme.
The project would ideally suit an MEng student in either Mechanical Engineering or Electrical Engineering, although other students can be considered. It is funded by a Bridging the Gaps award, at a rate of £220/week and will last for 10 weeks. Key deliverables are specimen production, development of the test method, combined electro-mechanical tests and a brief report. Training will be provided where needed.
