The space charge accumulation and decay at low density polyethylene (LDPE)/(LDPE- montmorillonite (MMT) nanofiller composite) interfaces were investigated using the step electroacoustic (SEA) method. A three-layered specimen was polarized under dc voltage at 90 °C. After cooling under field, the short circuit currents as well as SEA signals were measured during TS discharging of the sample. The MMT nanofillers affect the electrical properties, particularly conductivity of composites and play an important role in charge distribution. LDPE/LDPE-MMT interfaces act as carrier traps and favour accumulation of charges at higher temperatures.
