摘要: 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.

Abstract: Akind of amphiphilic oligomer-polymaleic acid octadecanol ester(PMA) with dif-ferent ratios of carboxylic group to hydrocarbon chain was synthesized with polymaleic anhy-dride and octadecanol- Then as spread materials, a series of CdPMA LBfilms were preparedon the subphase containing CdCl,.With FTIRand small angle X-ray diffraction, the effectsof different ratios of carboxylic group to hydrocarbon chain and experimental conditions onthe ordered structure of CdPMA LBfilms were characterized.We concluded that, in the caseof high constant surface pressure(3OmN/m) and high dipping speed (10 cm/min), the CdP-MAwith a lower ratio of carboxylic group to hydrocarbon chain could give a high orderedpure Y-type LBfilms, while the CdPMAwith a high ratio could not.
