Abstract

A new method of preparing SiO_x/LDPE nanocomposites has been investigated basing on mixing high boiling point organic silica sol and melting LDPE directly. The electrical properties of SiO_x/LDPE nanocomposites such as electrical treeing and space charge have been analysed by test datum. The dispersion of the nanocomposites is characterized by scanning electronic microscope. When the amount of SiO_x added is 1.5wt%, the nanocomposites with a particle diameter of 55 ~ 96 nm can be successfully prepared by the new method. The SiO_x in composite material can restrain the space charge and increase the tree initiation voltage as well as inhibit the growth of electrical trees.
