Abstract :
The electrical conduction of oil/polymer composite was investigated using surface-treated PP (polypropylene) films. The polymer films used were biaxially oriented PP films (thickness 22 μm) and rough-surfaced PP films. The insulating oil used was diarylethane oil (viscosity 6.3 cSt at 25°C). The origin of the carrier in the oil/PP system is shown to be local in the PP surface. Impurities in the PP surface region are much more numerous in the case of the rough films. The electrical conduction of the oil/PP system is strongly affected by the oil/polymer interaction
