Blends of thermoplastic cornstarch (TPS) and chitosan (TPC) were obtained by melt extrusion. The effect
of TPC incorporation in TPS matrix and polymer interaction on morphology and thermal and mechanical
properties were investigated. Possible interactions between the starch molecules and thermoplastic chitosan
were assessed by XRD and FTIR techniques. Scanning Electron Microscopy (SEM) analyses showed a
homogeneous fracture surface without the presence of starch granules or chitosan aggregates. Although
the incorporation of thermoplastic chitosan caused a decrease in both tensile strength and stiffness, films
with better extensibility and thermal stability were produced
