Abstract

A series of water-soluble carboxymethyl chitosan/poly(L-lactic acid) (CMCS/PLLA) blend films with various poly(L-lactic acid) mole contents were prepared by the solution casting method. Surface morphologies of CMCS/PLLA blend films were investigated by scanning electron microscopy. Thermal, mechanical and chemical properties of the polymer blend films were studied by differential scanning calorimetry, thermogravimetric analysis, tensile tests and surface contact angle tests. It was displayed that the introduction of poly(L-lactic acid) could modify the properties of carboxymethyl chitosan films.
