Electrical properties of composite material containing microvaristor and semi-conductive whisker

Microvaristors are used particularly as lightning arrestors. In another case, they are used as the electrical field grading materials. Additionally, we especially focused on their low volume resistance at the composite material of the microvaristors to use it as the anti-electrostatic coating. In the previous study, we found a solution to disperse microvaristors uniformly. In that study, we used semi-conductive whiskers to disperse microvaristors uniformly and connect electrically to make conducting paths. In this paper, we focused on the adding of the semi-conductive whiskers as secondary particles to the matrix and measured electrostatic charging properties.
