摘　　要： 聚酰亚胺（ＰＩ）是一种高性能聚合物材料，通过Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔ膜（ＬＢ膜）技术实现ＰＩ分子排列的有序化，可以使ＰＩ的某些性能更充分体现出来。详细总结了ＰＩＬＢ膜的制备方法，对其在气体分离、光敏性、液晶取向、介电以及光电导等方面性质的研究现状进行了较为全面的综述，对ＰＩＬＢ的研究和应用前景作了简要展望。 Polyimide(PI) is a kind of versatile polymer with high performance. By using Langmuir-Blodgett (LB) film technique to construct a highly ordered aggregated structure, its properties and functions will be conducted more thoroughly. In this paper, the preparation methods of PI LB films were reviewed. Their properties concerning gas separation, photosensitivty, liquid crystal alignment, dielectric and electrical properties and photoconductivity were discussed extensively. At the same time, the potential applications of PI LB films were described briefly. 
