Abstract

Poly(vinyl alcohol) (PVA) can be used in many applications such as packaging and biomedical application . In this study, Oil Palm Empty Fruit Bunch (OPEFB) was used as fiber to incorporate into the PVA and coupling agent which is Glut Palmitate (GP) was used. PVA/OPEFB was prepared by using solvent casting method. This research aim to prepare PVA/OPEFB at various composition 0, 10%, 20%, 30%, 40% of OPEFB loading. PVA/OPEFB composites before and after GP was added have been analyzed by using tensile test, FTIR, DSC, water adsorption and density test. The tensile stress, Young modulus and elongation at break are decreasing as increasing fiber into the composite. Addition of GP increase 12% tensile stress of the composites. Composites 80/20 GP has lower intensity of hydroxyl group compared to pure PVA and composites 80/20 in the FTIR spectroscopy analysis. The crystallinity of the composites has increase 33% when incorporate with GP in DSC analysis. Besides, composites with 80/20 has the higher water adsorption than composites of 80/20 with addition of GP. Moreover, the density of the composites raises as the increase of percentage of fiber. Therefore, addition of GP enhance the thermal and mechanical of PVA/OPEFB composites.
