Abstract :
In this paper, space charge distributions and dielectric properties, such as volume resistivity and ac breakdown strength were studied in low-density polyethylene (LDPE) and its composite by adding nano-ZnO nanofiller before and after corona aging for several days. It was found that a small amount of ZnO nanoparticles could effectively improve corona-stabilization of LDPE matrix. Fourier Transformed Infra-red (FTIR) spectrum of the specimens was also investigated to reveal the change of microcosmic structures. The results showed that a weaker carbonyl absorption peak appeared in LDPE/ZnO nanocomposite than in LDPE. A proper explanation was given according to corona-degradation theory of polyethylene.
