Physics & Astronomy

Liquids, colloids, polymers, foams, gels, membranes, biological materials and therefore life itself are just a handful of examples of soft matter.

With many internal degrees of freedom with weak interactions between the structural components, soft matter sensitive to the environment enabling functional materials to be created.

Soft matter can be found throughout industrial and technological applications. Whether it’s packaging, adhesives, detergents, cosmetics, medicines, fuels, rubber tyres, or paints, soft matter physics is central and essential to understanding, designing and optimising these products.

Shear Banding in Polymer Solutions?

Do polymer solutions "shear band" or not? Peter Olmsted and James Adams have shown that current theories are consistent with interpretations of both shear banding (unstable flow) or stable flow. However, which results one finds depends on the rheometer used! The message is that one needs to be very careful when interpreting experiments on the non-linear rheology of entangled polymeric fluids!
