【摘要】 用偏振ＦＴＩＲ－ＡＴＲ方法研究１～９层花生酸铒ＬＢ膜结构，结果表明，在适当条件下花生酸铒可以形成稳定的ＬＢ膜。利用单轴及双轴取向模型分析了不同层数ＬＢ膜的结构与取向，１层与３层以上的花生酸铒ＬＢ膜的结构是不同的。单层ＬＢ膜内脂链的取向角为３９°，并且是双轴分布，在ｘｙ轴投影的角度为４１°，３层以上花生酸铒ＬＢ膜的结构为单轴取向，取向角为２１°。更多还原

【Abstract】 Polarized FTIR- ATR studies on LB films of erbium arachidicate with l～9monolayer sug- gest that stable erbium arachidicate LB films can be prepared under proper conditions. Based on uni- axial and biaxial orientation models ,the analysis on orientations and structures of LB films indicatesthat structures of the first monolayer are different from that of multilayers. The orient angle of thefatty chain in the first layer is 39°,it’s biaxially oriented,and the projected angle on xy plane is 41°. In multilayer films the orient angle is 21°,it is uniaxially oriented.更多还原
