Development of bio-plastic synthesis have garnered many researchers' attention to turn the chemical plastic polymers into biocompatible plastics, such as using biologic enzymes for manufacturing, or using eco-friendly biomass as base materials. Regarding that above mentioned, poly(Lactic acid) (PLA) has received much attention such in food chemistry, electronics, and car industries due to biocompatibility, biodegradability, and/or non-toxicity. In this research, poly(L-lactide)(PLLA)s were synthesized, composed of L-lactide via bulk ring-opening condensation polymerization with a series of the mixtures of metal-based catalysts. The effect of metal oxide as a co-catalyst to molecular weights of polymers, and the effect of shape of the Zinc oxide (ZnO) nanoparticle catalyst as initiator/co-catalyst in the ring-opening polymerization will be given in the meeting. |
