Electrical conductivity and moisture uptake studies of low density polyethylene octylnanosilica composite

Abstract

In this paper, we report on the time dependent DC-conductivity response at constant electric field of unfilled low density polyethylene (LDPE) and its composites containing untreated and octylsilane treated silica in ambient and dry atmospheres. The conductivity of both composites decrease with time under dry conditions and increase with time in ambient atmosphere. The dielectric response of dry and wet silica polyethylene composites is studied by dielectric spectroscopy
