PVDF基介电复合材料的研究进展

摘要

聚偏氟乙烯(PVDF)基介电复合材料因具有加工性能好、介电损耗低、介电常数高等优点而成为现今介电复合材料领域主要的研究对象.对当前国内外PVDF与不同维数(0 维、1 维、2 维)填料共混所得 PVDF 基介电复合材料的制备方法、功能化改性及介电性能的研究进展进行了系统的综述,并对其研究和应用趋势进行了展望.%Poly (vinylidene fluoride)(PVDF)based dielectric composites have become the main research obj ect in the field of dielectric compositesbecause of their good processability,low dielectric loss and high dielectric constant.In this paper,the research progress on the preparation techniques,functional modification methods and dielectric properties of PVDF based dielectric composites containing different dimensional (0-D,1-D and 2-D)fillers was summarized,and the research and application trend was also prospected.
