| Abstract: | In this study, we aim at facile fabrication of biodegradable polyester nanocomposite films with homogenous dispersion of ZnO nanoparticles. An environment friendly multi-functional biodegradable polyester resin has been synthesized using polyethylene glycol (PEG), lactic acid (LA) and maleic anhydride (MA) as monomers. ZnO nanoparticles were synthesized by hydrothermal method. As prepared nanoparticles were characterized by particle size analyzer, FE-SEM (Field emission scanning electron microscopy) and TEM (Transmission electron microscopy). Biodegradable ZnO/polyester composite films with 0.25, 0.50, 0.75 and 1.0 wt% of ZnO nanoparticles were fabricated by solution casting method. Experimental results revealed that incorporation of ZnO nanoparticles lead to substantial improvement in UV protection, antimicrobial behaviour and thermal stability, while retaining the biodegradable nature of the films. |
