Abstract:
Biocompatible and biodegradable polymers became very important and gained a lot of attention from both biomedical and ecological outlook in the past decade(1). Among most popular and important biodegradable polymers are aliphatic polyesters (2,3) such as poly(3-hydroxybutyrate), poly (ε - caprolactone), poly(glycolic acid) and poly(lactic acid) (PLA), whereby PLA received the most attention due to its renewable resources, biodegradation, biocompatibility as well as excellent thermal and mechanical properties. In this work PLA/ZnO nanoparticle composites were studied as a function of the ZnO weight percentage (1,2 and 5 wt%) in relation to the use of PLA. The resulting composites were characterized by DSC, TGA measurements, and FTIR spectroscopy. The morphology of the PLA/ZnO nanocomposite films and the distribution of the ZnO nanoparticles were also characterized. The antibacterial activity of the PLA/ZnO films were examined against Gram-negative and Gram positive bacteria.
