Abstract

Under high temperature conditions, polyethylene particles are dissolved in xylene in a flask reactor, and organic molecules such as peroxymethylenetetraimide and tetramethylbenzoquinone dimethyl methane with different concentrations are added to the mixture. At 150 ℃, the sample is hot pressed into a thin film. The characteristics of DC decomposing power as well as room charge distribution were measured. The experimental results show that doping small molecules can not only effectively restrain the gathering of room charge, but also enhance the DC decomposing power. Doped small molecules can introduce deep wells to capture space charges and disperse carriers, thereby reducing the number, mobility and energy of carriers.
