摘　　要：聚酰亚胺具有一定的吸水性,这导致其在使用中出现了一系列问题,如薄膜与金属黏合失效、封装破裂、金属腐蚀及介电性能下降等。为解决这一问题,综述了降低聚酰亚胺材料吸水率的主要方法:分子主链引入含氟结构、引入柔性结构、引入含硅结构、填料改性,等等,以提高聚酰亚胺耐热性、耐腐蚀性、力学性等,使其广泛应用于航空航天、微电子、纳米、液晶、分离膜、激光等高科技领域。Polyimide can absorb a certain amount of water,resulting in film and metal bond failure,metal corrosion,package rupture,and dielectric degradation.In order to solve the problems,the study summarizes the main methods of the water absorption of polyimide,the introduction of molecule backbone into fluorine-containing structure,flexible structure,silicon structure,filler and modification,etc.to improve polyimide thermostability,corrosion resistance,and dynamics,etc,and make it widely applied in high-tech field,including aerospace,micro-electronics,nanometer,liquid crystal,separating film,and laser,etc.
