摘　　要：综述了国内外聚酰亚胺(PI)/纳米SiO2复合材料的最新研究进展,重点阐述了溶胶-凝胶法制备PI/纳米SiO2复合材料的机理,详细讨论了该复合材料的性能(微观结构、物理机械性能、耐热性、耐化学性和成型加工性等)及其在各领域中的应用,总结了PI/纳米SiO2复合材料存在的具体问题和未来的发展趋势。The current research progress of the polyimide（PI）/nano-SiO2 composites was introduced at home and abroad, and the preparation mechanism of PI/nano-SiO2 composites by sol-gel method was reviewed emphat- ically. The composites performance （microstructure, physical mechanical performance, heat-resistant, chemistry- resistant and molding process） and applications in various fields were discussed in detail. The existent idiographic problem and future development trend are summarized about the PI/nano-SiO2 composite in relevant fields.
