Electrical Properties of Polyethyleneterephthalate Film for Transducer

변환기용 PET 박막의 전기적 특성

In this paper, we have investigated the physical, dielectric and electrical conduction properties of polyethylene terephthalate(PET) film due to temperature variation. From FT-IR spectrum as an analysis of physical properties, the strong absorption in wavenumber 1019[$cm^{-1}$], 1266[$cm^{-1}$], and 1752[$cm^{-1}$] observed by the C=O and benzene ring. the characteristics of volume resistivity used to highmegohm meter is measured from 1 to 10 minutes when the specimen applied the voltage according to the step voltage appling method. and dielectric characteristics were measured in the temperature range from room temperature to 120[$^{\circ}C$] due to frequency variation.. also we measured in the voltage rang of 1[V] to 20[V] according to the voltage application method.
