This is part of an on-going investigation into nano/micro scale sized polymer fibres at the University of Reading, prepared through the process of electrospinning. Currently we are looking at electrospinning nanoscale composites from sustainable resources and in particular from food waste materials. We seek the time to measure high quality SANS data on isotopically labelled, high concentration whey protein, polyethylene oxide composite solutions in order to measure the correlation length of the polymer chain components in solution and to understand the complex relationship between polymer composition/ time and the ability to form fibres. This data will be compared with that obtained from fibres prepared from these solutions.
