Abstract
The enhanced thermal, electrical and mechanical properties can be explored by polymer based nanocomposites. In the present work, initially nanocrystalline Zinc Oxide particle is successfully synthesized at room temperature by sol gel method using Zinc acetate and Oxalic acid. The material is characterized using XRD, to determine the grain size. The nanocomposites are prepared for pure, 1wt% 2 WT% and 3wt% by mixing and pouring the nanoparticles with the epoxy resin and appropriate amount of hardener into the mould. The obtained polymer sheet is characterized using thermal, electrical and mechanical studies to study glass transition temperature, AC conductivity, tensile and elongation properties of the ZnO/epoxy nanocomposites respectively.
