Characterization of chitosan/montmorillonite hybrid filled tapioca starch nanocomposite films

Biodegradable nanocomposite films from chitosan/montmorillonite (MMT) hybrid filled plasticized tapioca starch (TPS) were developed using a solution casting method. Chitosan was extracted from local shrimp shell resources with the degree of deacetylation of 60.85%. X-ray diffraction (XRD) analysis s...
