The Effect of Nano Zinc Oxide on Characteristic Bionanocomposite

Abstract

Demand of plastic is increasing along with the increasing use of plastics invarious fields. Plastics are hard to decompose biologically, so that it will give negative impacts to environment. One of ways to decrease those negative impacts is by using eco-friendly materials. Bionanocomposite is one of eco- friendly materials for plastics; this composite c a n b e m a d e f r o m natural polymer and nano particle. This research used nano zinc oxide as nano particle for bionanocomposite. Bionanocomposite can be used as packaging, semiconductor, and medical materials. This research aims to know t h e effects of various type of nano zinc oxide (nano zinc oxide from galvanic industry waste, commercial, and without nano zinc oxide), and concentration of poly vinyl alcohol (0.5%, 1%, and 1.5%) on the bionanocomposite characteristics. The produced bionanocomposites was analyzed based on its mechanical properties, morphology, and biodegradation. The result showed that nano zinc oxide have effects to tensile strength and elongation of bionanocomposite, it also produces homogenous structure. Bionanocomposite can be degraded for 4 weeks
