摘要：
The study describes the preparation and characterization of some biodegradable films obtained from PVA/PLA blends (100/0, 90/10, 80/20, 70/30), colloidal Ag-0 and other additives. Poly(lactic acid) was synthesized by melt polycondensation procedure of L(+)-lactic acid using manganese acetate as catalyst. The films were carried out by solution casting and evaporation of the solvents water/dioxane at ambient temperature. The films were characterized by IR spectroscopy, mechanical properties, thermal analyses (DSC, DTG) and optical microscopy.
