This paper evaluated the influences of silica nanoparticles on the dielectric properties, mechanical performances and glass transformation behaviors of epoxy resin by analyzing the temperature dependence of dc conduction and dielectric loss, impact test results and dynamic mechanical data, respectively. The particular attention was given to the correlation between the glass transformation behaviors,...
This paper reports on the role of silica nanoparticle surface treatment in affecting the morphology, charging current, frequency dependence of dielectric parameters, breakdown electric field and water treeing behaviors of linear low density polyethylene (LLDPE). Octyl-trimethoxysilane was used as a silane coupling agent for the surface treatment of the silica nanoparticles. The composite sample with...
Premature failure of XLPE cables can occur due to water trees increased the susceptibility of polyethylene insulation to breakdown, and extensive studies have been made to improve the resistance of polyethylene to water treeing in the past. In this study, we investigated the influence of the incorporation of silica nanoparticles and the surface modification of silica nanoparticles on the water treeing...
