Effect of ZnO Nanocomposite by Direct and In Direct Sonication Method

The zinc oxide well known for its dielectric property and the anticorrosion, widely used in solar cells. This section deals about the development of the both mechanical and electrical property of Kevlar by adding the ZnO nano composites inside vinyl ester resin. The zinc oxide mixed well with the polyvinyl ester resin without disturbing the chemical behavior of the ZnO. The synthesis of zinc oxide with polyvinyl ester resin done by the direct and indirect sonication process. The kevlar fiber taken as the specimen for this research. The ZnO � polyvinyl ester resin mixed together using the manual without affecting the hydrophobic behavior of the polyvinyl ester resin, the zinc oxide and polyvinyl ester resin mixed with hardener (HY956) with the standard ratio of 5:1. The size of zinc oxide is 75nm. The results show that the direct sonication process giving better tribological properties when compared to indirect sonication process. From the plot and tables it is understood that the kevlar performs superior with ZnO nanocomposites
