摘要
高介电聚偏氟乙烯(PVDF)复合材料因具有质轻、柔性好和易于加工等优点,在电子通信、新能源存储、航空航天等领域被广泛应用.目前PVDF基复合材料主要分为无机/有机复合体系和全有机复合体系两大类,但全有机体系因其化学工艺复杂等问题限制了其应用.文章综述了陶瓷粒子、金属粒子和碳系粒子三种无机填料在PVDF基介电材料中的应用现状及研究进展,其中重点介绍了碳系填料中的膨胀石墨、氧化石墨烯、碳纳米管、炭黑和碳纤维几种粒子改性PVDF介电复合材料的研究进展,并展望了无机填料在PVDF复合材料中的改性方向.
Abstract
High-dielectric polyvinylidene fluoride(PVDF)composites are widely used in electronic communications,new energy storage,aerospace and other fields due to their advantages of light weight,good flexibility,and easy processing.At present,PVDF matrix composites are mainly divided into two categories:inorganic/organic composite system and full organic composite system,but the application of full organic system is limited by its complex chemical process.This paper reviews the application status and research progress of three inorganic fillers in PVDF-based dielectric materials,namely ceramic particles,metal particles and carbon particles,and focuses on the research progress of expanded graphite,graphene oxide,carbon nanotubes,carbon black and carbon fiber in carbon fillers,and looks forward to the modification direction of inorganic fillers in PVDF composites.
