摘要
本文以均苯四甲酸二酐 (PMDA)和 4,4′-二氨基二苯醚 (DAPE)作主要原料合成的聚酰亚胺 (PI)为基体 ,以有机化蒙脱土 (MMT)为无机相 ,制备了聚酰亚胺 / MMT纳米复合薄膜。采用透射电镜 (TEM)、X射线衍射 (XRD)对薄膜微相形态结构进行了分析测试 ,考察了薄膜的拉伸强度、电气性能和热性能。
Polyimide/Montmorillonite (PI/MMT)Nanocomposite film was prepared by using pyromellitic dianhydride(PMDA) and 4,4′—diamino dipheny1 ether (DAPE) as monomers,as well as organic montmorillonite (MMT) treated by 16-decyltrimethyl ammonium chloride as inorganic reinforcement.We tested the mechanical,thermal and electrical properties of the PI/MMT film made with the flushing shaping technique.The results show that the tensile strength of film increases up to 78%,compared with the pure PI film,there is no significant change in electrical property.Besides,the thermal property is improved by delaying the degradation temperature of film.
