From the comparison of dynamic characteristics of surface charge between different functional die-lectric materials with micro voids and micron particles, the influence of voids and micron particles on the charge traps and stability of surface charge is investigated. The storing and retaining effects of inner voids are concluded. Meanwhile,a small amount of micron particle in polymer matrix can play an important role in the charge inhibition and increasing decay rate of surface charge. The study is of great significance on the applica-tion fundamental of insulation and functional dielectric materials.
