摘　　要：本文采用扫描电子显微镜/能谱仪(SEM/EDS)和傅立叶变换红外光谱仪(FT-IR)对一种液晶调光膜进行了结构及各层主要成分的分析。结果表明,该液晶调光膜的结构为上、下离型膜,上、下保护层,上、下电极层(ITO/PET),位于中间的液晶功能层,以及层与层之间的粘结层,共计13层。其中,上离型膜(上:即靠近粘贴玻璃的一侧),上、下保护层,以及上、下电极层的基材均为聚对苯二甲酸乙二醇酯(PET)。液晶功能层主要为聚合物分散液晶材料,其中,聚合物为聚氨酯类。SEM/EDS and FT-IR were used for the analysis of the structure of a commercial PDLC. The results showed that it contained 13 layers including release films, protective layers and electrode layers of both sides and between which there was a functional layer. The upper release film, upper protective layer and the base film of both electrode layers were all PET films. Besides, the polymer in the functional layer was confirmed to be polyurethane.
