Pyroelectricity of Drawn Poly(vinylidenefluoride) Films
연신된 폴리비닐리덴플루오라이드 필름의 초전성
Abstract
The pyroelectricity of poly(vinylidenefluorde) films prepared by varying the draw ratio and poling field was investigated. As the draw ratio and the electric field on poling of the drawn samples increased, so did the pyroelectric coefficient. But the effect of electric field on the pyroelectricity was greater than that of draw ratio. The pyroelectric and piezoelectric activities could be explained by the polarization using the thermally stimulated current. The relation between pyroelectric coefficient and piezoelectric stress constant showed a good linearity.
