碳材料/聚酰亚胺复合膜的研究进展

摘要

综述了近年来石墨、石墨烯和碳纳米管这3种碳材料与聚酰亚胺(PI)形成复合膜的研究成果。阐述了制备PI复合膜各个阶段采用的不同方法及其优缺点，再对所得复合膜的性能进行总结，评述了PI复合膜的机械性能、热性能以及与二者相悖的导电性能，最后指出了PI复合膜的不足与今后发展的方向。%The carbon materials(graphite,graphene,carbon nanotubes)with polyimide (PI)formed a composite film,and the research of PI composite film was reviewed in re-cent years.The preparation methods of PI composite film and their advantages and disad-vantages at each stage were described.And then the performance of the obtained compos-ite film was summarized .The mechanical properties and thermal properties of PI film as well as the electrical conductivity contrary to both were reviewed.Finally,the deficiency and the development direction of PI composite film were pointed out.
