Characterization Studies of Thermoplastic Starch Enhanced With [Emim][OAc

This study investigates the effect of using ionic liquid 1-ethyl-3-methylimidazolium acetate [Emim][OAc] as plasticizer for the improvement of thermoplastic starch (TPS) material. The physical and chemical properties of the TPS were studied and investigated in this project. The results of morphol...
