RESEARCH ON SYNTHESIZING POLYLACTIC ACID FROM KIEN GIANG’S NIPA PALM TREE (NYPA FRUTICANS)
Main Article Content
Abstract
Among biodegradable polymers, polylactic acid (PLA) and other derivatives are practical. This project aims to synthesize PLA from lactic acid (LA) pre-fermented, itself extracted from the sap of Nypa fruticans. The process begins with a 2-week stimulation process of the tree’s fruit cluster to obtain the sap. It is then lactic acid fermented with Lactobacillus plantarum and subsequently condensed, producing PLA. Through Fourier transform infrared spectroscopy (FT-IR) and hydrogen-1 nuclear magnetic resonance (1H-NMR), its structure was observed. PLA’s physical and chemical properties were determined based on the thermalgravimetric analysis (TGA). PLA made from the sap of Nypa fruticans is expected to replace the environmentally-unsustainable petrochemical-based polymer.
