摘　　要：在极端条件下,材料性能退化是引起航天器失效的主要因素,而摩擦运动部件的润滑失效是导致材料性能退化的关键所在.聚酰亚胺以其独特的耐高低温性能、优异的机械性能以及独特的自润滑性能而被广泛应用于航空航天等高新科技领域.因此研制适用于不同工况需求的高性能聚酰亚胺自润滑复合材料具有重大的意义.基于国内外研究进展,本文介绍了中国科学院兰州化学物理研究所近年来在极端条件下的聚酰亚胺自润滑材料研究成果,并对未来聚酰亚胺润滑材料的设计思路与发展趋势进行了展望.Under extreme conditions, the degradation of materials mainly caused the failure of spacecraft missions, but the lubrication failure plays an important role in this degradation. Polyimide, with its unique high and low temperature resistance, excellent mechanical as well as special self-lubricating properties, is widely used in high-tech fields such as aerospace. Therefore, it is of great significance to develop polyimide self-lubricating composites applied in different conditions. Based on research of both domestic and overseas, this feature article introduces the research progress in polyimide self-lubricating materials of Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences.Furthermore, the methods for designing polyimide-lubricating materials in the future and its development tendency are put forward.
