Electrical conduction of oil/polymer composite

Charging and discharging currents and thermally stimulated current in diarylethane oil/PP (polypropylene) and diarylethane oil/FEP were investigated experimentally. It was shown that the charging current of diarylethane/PP was enhanced by the oil/polymer interaction. The charging current of diarylethane/FEP was affected by F atoms in FEP. Negative carriers in oil were considered to be trapped near the FEP surface and to form a space charge, which enhanced the discharging current and TSC in negatively charged oil/FEP.<<ETX>>
