ANF/PMIA复合薄膜的制备及其击穿强度研究
Study on Preparation and Breakdown Strength of ANF/PMIA Composite Film
摘要
Abstract
Aramid nanofibers(ANF)were prepared via a deprotonation method,and subsequently compounded with poly(m-phenylene isophthalamide)(PMIA)to obtain A-P composite films.Based on the abundant active groups on the ANF surface and its excellent physicochemical properties,the effects of ANF on the mechanical properties,breakdown strength,and dielectric properties of A-P composite films were investigated.The results indicated that when the ANF mass fraction was 0.5%,the tensile strength and breakdown strength of the A-P composite film increased to 96.9 MPa and 373.4 MV/m,respectively,representing an improvement of 23.4%and 49.9%compared with pure PMIA.ANF enhanced the dielectric constant of the A-P composite film while maintaining dielectric loss below 0.1 across the test frequency range,meeting the application requirements for high-insulation fields.The findings provided a reference for the development of novel organic insulating films.关键词
