Rheology and composites

The behaviour of materials under flow is essential to understand for many processing, manufacturing and product uses. We use controlled rheology experiments on well defined samples to study their behaviour in simplified flow conditions and combine with theory, modelling and other experimental techniques to understand the complex behaviours of modern materials.

Research Interests

Research in Dr Thompson’s group is focused on the physical chemistry of polymers and particularly their fascinating behaviour at exposed surfaces and buried interfaces. Within this area, there are two main themes: (i) the relationship between chemical functionalisation of polymer and their self-organisation,[1, 2] and (ii) the exploitation of unusual process environments to control this behaviour.[3, 4] As well as addressing fundamental polymer science problems, the group collaborates with actively with industry and other research groups to address diverse topics such as surface modification, rheology (flow) problems, polymer electronics[5] and nanocomposites.[6]

Influence of solvents on polymer adsorption and diffusion

-why bake, when you could boil, steam or deep fry!?

Polymer processing frequently makes use of organic solvents and we have used ion beam and optical techniques to explore for the first time the relationship between the ingress of a penetrating solvent vapour or nonsolvent and the interdiffusion of polymer chains that can accompany this process. Not only does this allow us to understand how to make efficient use of organic solvents, but is leads to new opportunities in polymer self-organisation. We have also shown for the first time that polarity, pH and ionic strength of a contacting non-solvent can all be harnessed to deliver different kinds of surface modification.
