摘要

The surface performance of insulating materials is essential for the safety and stability of electrical equipment and system. It is an effective method to improve surface hydrophobicity of insulating materials to enhance surface flashover voltage. In recent years, the increased focus has been given to plasmas powered by pulsed power sources, because of their advantages of high efficiency and strong reduced electric field, making it easier for the excitation of reactive particles. Moreover, the thermal effect of these sources in the processing is greatly limited due to the extremely short excitation time. Through interactions between various active particles generated by pulsed discharge and insulating material surface, physical and chemical reactions are set off during energy interchange. Surface physical and chemical properties of insulating materials are changed through functional group implement or film deposition, and surface insulating performance are improved accordingly. The surface modification results can be manipulated by controlling treatment conditions and methods, in order to satisfy multiple requirements of various insulating materials. In this chapter, typical insulating material polymethyl methacrylate (PMMA) and epoxy resin (EP) are taken as the example to introduce the method and results for improving the hydrophobicity, flashover voltage, surface conductivity. The mechanisms of surface performance improvement are analyzed from the view of interactions between the plasma and the treatment surface.
