Starch Based Biocomposite from Sago (Metroxylon sagu) with Nano-Chitosan reinforcement : Mechanical and Thermal Characteristics

A biocomposite system incorporating sago starch and nano-chitosan (SS/NCS) were developed by casting and solvent evaporation method. The purpose of this experiment for characterization of the film based on sago starch (SS) with a variation of the addition of nano-chitosan (0, 2, 4, 6 and 8% by weigh...
