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 uegative impacts to environment. One of ways to decrtase those negative impacts is by using eco-friendly materials. Bionanocomposite is one of eco- friendly materials for plastics; this composite can be made fro 111 natural polymer and nano particle. Thi~ 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 the effects of various type of nano zinc oxide (nano zin'" 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 an11lyzed based on its mechanical properties, morphology, and biodegradation. The result showed that nano zinc oxide have effects to tensile strength and elongation of bionanocompos ite, it also produces homogenous structure. Bionanocomposite can be degraded for 4 weeks. ·
