research interests
My research interests are mainly in the field of solid solid interactions, particularly where organic polymers form one of the solid bodies. In particular I have been interested in those factors which are responsible for the friction, adhesion and wear of organic materials. Specifically I have researched and continue to conduct research into the:
Shear strength of thin organic films
- adhesion between highly elastic bodies
- friction and wear of polymers: the use of fillers
- diffusion of surface active additives in polymers
- slow diffusion and self diffusion of high molecular weight materials in polymers
- adsorption of organic polymers onto the surface of solids and the thickness and structure of these layers
- deformation of solids at high rates of strain
- transport of powders
- plasticisation of polytetrafluoroethylene in hydrostatic gas media
- abrasion and scratching of polymers
- influence of gamma radiation on the mechanical and tribological properties of polymers
- lubrication of engineering polymers
- action of mould release agents
- surface rheology of biopolymers
- surface modifications of polymers (chemical and topographical)
- compaction of powders
- near net shape forming
- design and construction of viscosity and density probes
- mud rheology
- paste processing
- polymer solution rheology at high pressures
- tribology of composite materials and the relationship between tribological performance and mechanical properties
- hardness of polymers and composites
- gas sorption in polymers
- surface properties of fibres
- mechanical properties of fibre assemblies and the action of fabric conditioners
- properties of gels
- gas induced damage in polymers during explosive decompression
- high speed winding of polymer films
- numerical simulation (finite element (FE)) of solid deformations
- deformation of small particles
- supercritical extraction and processing
- plastisation of polymers
Other expertise:
- ceramic processing, near net shape forming
- reaction injection moulding (rim) simulation
- composites for structures and brakes
- polymer foaming
- inverse gas chromatography
- processing of uranium dioxide powders
- food process engineering
- cell deformation
- hardness of tissue
- scratching of polymers
- atomic force microscopy (AFM) and nanohardness
Future research:
- plant fouling and hygiene
- skin deformation mechanisms
- manufacture of solid oxide fuel cell element
- microhardness and nanohardness of polymers
- fourier transform (FT) Raman and Fourier transform infrared (FTIR) of polymers
- vapour condensation on polymers
- wetting of polymers
- binder burn-out in ceramics
- hardness of polymers
- gas sorption in polymers
- explosive decompression of polymers
- rheology of foods
- supercritical enhanced processing
