Abstract: By using ESCA, We observed the chemical composition of both surfaces of polyvinylidene fluoride film produced by inflation method. Higher fluorine content was detected on the surface of the film which contacted with a steal winder at film making process. This means that the orientational polarization of C-F dipoles at the film surface has already occurred at manufacturing stage. The electrical conduction properties such as short-circuit current and I-t chracteristics were measured. A large short-circuit current obaying thermal activation process was observed without applying voltage. On a I-t chracteristics under applying a dc voltage, current peak and/or shoulder were observed depending on the polarity of applied voltage. We disccussed these conduction phenomena taking the C-F dipole orientation into consideration.
