Preparation and characterization of morphological and mechanical properties of antibacterial, biodegradable polymer material based on polylactic acid

The goal of this contribution was to investigate the morphological and mechanical properties of a ternary blend composed of PLA, chitosan and LDPE. In addition, effect of incorporation of LLDPE-g-MA was also investigated. It was observed that chitosan addition enhanced stiffness of PLA/PE blend while decreased the toughness and tensile strength. It was demonstrated that LLDPE-g-MA beyond the 15 wt% started to play its role as compatibilizer and promote the toughness of the blend
