Thus proposal seeks to explore the nature of electrospun composite fibres where the polymeric material contains a substantial quantity of biopolymer obtained from food waste - we have established that significant quanties of celluolose (obtained from carrots but potentially from sugar beet pulp) can be incorporated into electrospun fibres and have extended this concept to whey protein. We wish to extend our recent work on polymer blends to these composite systems. We shall investigate fibres prepared from deuterated polystyrene (electrospun from DMF solution) and the additive materials, and we shall also explore the possibility of partial deuteration of both cellulose and the protein through proton exchange in D2O. It is intended that the data obtained will inform us as to the behaviour of the polystyrene in the system and also the nature of the phase separation of the two components.
