摘要

随着电子、信息和电力工业的快速发展

高储能密度介质材料受到了越来越多的关注。为制备高储能密度的电容器用介质材料

研究以溶剂共混法（DMF作为溶剂）获得Al/BT/PVDF和Ag/BT/PVDF三元复合材料

并对制成的三元复合材料的相对介电常数、击穿场强和储能密度进行测试分析

测试结果表明:复合材料的介电常数与混入金属前相比变化不大;当铝含量为2.0%

BT含量为7.5%时

复合材料储能密度达到了2.0 J/cm

提高到纯PVDF的5倍。

Abstract

With the rapid development of electronics

information and electric power industry

high energy density dielectric material is of more and more interest. For preparing the dielectric materials with high energy storage density for capacitor

AI/BT/PVDF and Ag/BT/PVDF three-phase composites material are obtained by the solvent blending method（DMF as solvent）

the relative dielectric constant

dielectric breakdown field strength and energy storage density of the three-phase composite material are tested and analyzed. It is shown by the test result that the relative dielectric constant of the composite material remains almost unchanged compared to it before mixing into the metal and in the case of the content of Al at 2.0% and BT at 7.5%

the energy density of the composite material is

up to 2.0 J/cm

which is 5 times of pure PVDF.
