Abstract

DC breakdown in polyvinylidene fluoride (PVDF) films was studied. It was found that the interface between the metal electrode and the polymer film is very important in determining the breakdown voltage. When the positive electrode was blocked by inserting a thin layer of insulating polymer between the PVDF film and the metal electrode, the breakdown voltage decreased drastically. The breakdown behavior was also studied as a function of the thickness of the polymers used to block the electrode. The results obtained agree with the observation that the piezoelectricity of PVDF is dependent on the metal-PVDF interface a dependence which is believed to be directly related to the piezoelectricity of PVDF
