摘要 该文以一种具有新型介电特性的聚丙烯基纳米复合薄膜为研究对象, 通过与德国创思普公司以及我国百正公司的双轴拉伸聚丙烯(BOPP)薄膜进行对比, 基于试验重点研究三类薄膜热老化行为对薄膜结构变化和介电性能的影响, 发现随老化时间的延长, BOPP的相对介电常数和损耗均有所升高, 而复合薄膜的相对介电常数下降;另外, 所有样品的储能特性都随着热老化时间的增加而下降。研究结果表明, 热老化前后高介电聚丙烯基纳米复合薄膜的相对介电常数和储能密度均优于两种BOPP薄膜。因此聚丙烯基纳米复合薄膜是一种高相对介电常数、具有较好储能性能电介质薄膜, 可用于制备具有高储能密度的薄膜电容器。

Abstract:A polypropylene-based composite film with improved dielectric property was studied by comparing with the biaxially oriented polypropylene (BOPP) films of German Treofan company and China Baizheng company. The effects of heat aging behavior of three types of films on the film structural changes and dielectric properties were studied. It was found that both the relative dielectric constant and loss of BOPP increased with the aging time, while the relative dielectric constant of composite films decreased. In addition, the energy storage characteristics of all three samples decreased with the increase of heat aging time. The results show that the relative dielectric constant and energy density of the high-k polypropylene composite films are better than those of two BOPP films. Therefore, the high-k polypropylene nanocomposite film is a dielectric film with high relative dielectric constant and good energy storage performance, which can be used to prepare film capacitors with high energy storage density.
