摘要
本文在理论上分析了TGS·PVDF复合材料的介电和热释电特性,给出了其特性随样品厚度、两相体积比和TGS颗粒度变化的实验结果。区分了复合材料的热释电效应和退极化效应,得到了正确的热释电系数测量结果。
The dielectric and pyroelectric properties of TGS·PVDF composite material films are analyzed in theory.The relationship between these two properties and thicknesses of samples, as well as volume ratios of components and sizes of TGS crystal grains,is given experimentally. The pyroelectric effect is distinguished from the depolarization effect so that the correct pyroelectric coefficients of TGS· PVDF composite films are obtained.
