Abstract

Space charge is formed at the interface of two different materials to maintain the continuity of current when the electric field is 25 kV/mm, while packet-like charge appears only in the LDPE at 100 kVImm. These phenomena are explained by assuming that the nanofillers effectively suppress the increase in conductivity induced by the high electric field. Related work done previously by the authors is also briefly reviewed
