Space charge and electrical conduction in maleic anhydride-grafted polyethylene

Abstract

The space charge behavior such as charge distribution and electrical conduction of maleic anhydride grafted LDPE (LDPE-g-MAH) was investigated. Heterocharge was found in LDPE and it decreased with increasing MAH graft ratio in LDPE-g-MAH. Conduction currents also decreased with increasing MAH graft ratio. The relationship between the space charge behavior and the electrical conduction characteristics in LDPE-g-MAH is discussed.
