要約(英語): Previously, the pulsed electroacoustic method could not separate the true charge and the polarization charge at the sample-electrode interface. This is because the positional resolution of the measurement device is not sufficient. In this study, we attempted to separate the true charge and the polarization charge by applying a pulse voltage and a DC voltage to the sample through an air gap. The polarization charge is formed by dielectric polarization, so the permittivity can be calculated by measuring the amount of the polarization charge. Therefore, in this paper, we measured the polarization charge of polymeric insulating materials with different relative permittivity when applying step voltage as an initial study. As a result, it was observed that the charge signal reflected the polarization charge at the sample-air interface. Consequently, it was suggested that the PEA method enables to measure the permittivity while observing the charge distribution inside the sample.
