Abstract
Recently, polymer nanocomposite has been attracting much attention as an emerging insulating material. In this paper, we measured space charge distribution in low-density polyethylene (LDPE)/MgO nanocomposite at room temperature and 90 °C. At room temperature, while a huge amount of packet-like charge moving from the anode to the cathode is observed in the base LDPE, such packet-like charge is not observed in the MgO-added nanocomposites. On the other hand, at 90 °C, while injection of negative charge from the cathode is dominant in the base LDPE, the filler addition significantly suppresses the injection. As a consequence space charge is barely formed in the 2-phr MgO-added sample at the two temperatures.
