摘要
随着电子技术的不断进步,目前商业化应用最为广泛的双向拉伸聚丙烯(BOPP)因其较小的储能密度已不能满足电子产品的要求。在众多可作为电介质薄膜的材料中,聚偏氟乙烯(PVDF)基纳米复合材料因其介电常数高、加工性能好等优点受到广泛关注。本文在介绍电介质复合材料理论模型的基础上系统综述了目前PVDF基纳米复合材料的主要制备策略:填料改性、多相共混及构建新颖结构,并对PVDF基复合储能材料的发展前景进行了展望。
With the continuous advancement of electronic technology,the oriented polypropylene(BOPP),which is currently the most widely used in commercial applications,cannot meet the requirements of electronic products due to its small energy storage density.Among many dielectric film materials,polyvinylidene fluoride(PVDF)-based nanocomposites have received widespread attention due to their high dielectric constant and good processing properties.In this paper,the theoretical model of dielectric composites was introduced,the main preparation strategies of PVDF-based nanocomposites:filler modification,multi-phase blending,and construction of novel structures,were reviewed systematically,and the development of PVDF-based composite energy storage materials was prospected.
