Synthesis and Characterization of Polyethylene /Silica Nano Composite

Abstract

Polyethylene/silica Nano composite was synthesized in different concentrations (2%, 3%, 4%, 10%, 20%, 30%, 40%, and 50%) The samples were subjected to physical evaluation; the result showed that the amount of silica is changed the optical properties (the maximum absorbance was 284 nm) and the composite had moderate refractive index in infra red region but it is de- shielding in part of ultra violet region. Mechanical properties was enhanced .the highest load was 5.4kg to sample that contain 4% weigh of silica.
