PHYSICOCHEMICAL STUDY OF THERMOPLASTIC STARCH(TPS) USING IONIC LIQUID AS PLASTICIZER

This research investigates the physicochemical and hygroscopic properties of thermoplastic starch (TPS) an alternative biodegradable material. The material is formed from starch, Ionic liquid (IL) as plasticizer and rice straw fibre (RS) as fillers. TPS is synthesised through starch gelatinization p...
