Abstract

The development of biodegradable nanocomposite has led to improved properties of PLA. This research was carried out to investigate the addition of graphene nanoplates (GNP) as a filler in poly-lactic acid/ liquid natural rubber (PLA/LNR) blends on the tensile and thermal properties. The nanocomposites were prepared by melt blending method using internal mixer with 100rpm for 14 minutes. LNR was used as a toughening agent in this nanocomposite. The weight ratio of PLA: LNR fixed at 90: 10. The content of GNP added was 0.25 wt%, 0.50 wt%, 0.75 wt% and 1.00 wt%. The results have shown that the addition of 0.75wt% GNP exhibited the maximum in tensile strength at 24MPa and elongation at break at 2.5%. Scanning electron microscope SEM micrograph showed good dispersion of GNP in PLA. The thermogravimetric analysis (TGA) proved that the presence of GNP delayed the decomposition process of nanocomposites. Overall results showed that the addition of GNP improve the properties of PLA ideally.
