由聚马来酸杆和十八醇合成了一系列不同羧酯比的聚马来酸十八醇酯（PMA），并以其为成膜材料、CdCl2水溶液为亚相制备了一系列聚马来酸十八醇酯镉盐（CdPMA）LB膜．借助小角X射线衍射和红外吸收光谱表征了成膜条件及羧酯比对CdPMA膜有序结构的影响．在较高膜压（30mN／m）和快速提拉（10cm／min）条件下，低羧酯比的CdPMA可得到有序性很高的Y-型LB多层膜；高羧酯比的CdPMA得不到高有序性的LB多层膜．
A series of polymaleic acid octadecyl ester (PMA) with different carboxyl ester ratios were synthesized from polymaleic acid and octadecyl alcohol. A series of polymaleic acid Octacosanol acid cadmium salt (CdPMA) LB film. The effect of film formation conditions and carboxylate ratio on the ordered structure of CdPMA films was characterized by small angle X-ray diffraction and infrared absorption spectroscopy. At higher membrane pressures (30 mN / m) and rapid pull-up (10 cm / min), YPLC LB multilayer films with low carboxylate ratio were obtained, and high order carboxyl-terminated CdPMA No highly ordered LB multilayer film was obtained.
