中文摘要：
研究了十八胺（ODA）及其与硬脂酸（SA）混合单分子膜在导电聚合物聚3,4-乙烯二氧噻吩／聚苯乙烯磺酸（PEDOT—PSS）胶体亚相上的成膜行为和复合LB膜在室温下的电学性能．结果表明：ODA—SA／PEDOT—PSS复合LB膜具有更好的成膜性能，表面粗糙度小且稳定可控，薄膜具有较好的有序结构；ODA～SA／PEDOT—PSS膜电导率高于ODA／PEDOT-PSS复合LB膜，其电导率呈各向异性，水平电导率（σⅡ）与垂直电导率（σ⊥）之间相差3—4个数量级，Ⅰ-Ⅴ曲线呈指数关系，为典型的电子隧穿类型．
英文摘要：
The film-processing ability of ODA and mixed ODA-SA monolayer on poly （3, 4- ethylenedioxythiophene）-poly（styrenesulfonate） （PEDOT-PSS） colloidal dispersion subphase and the conducting performance of the PEDOT-PSS LB films were investigated. It is shown that better film-processing ability of PEDOT-PSS can be achieved by spreading ODA-SA mixed monolayer on the PEDOT-PSS subphase. The surface of ODA-SA/PEDOT-PSS mixed LB films appears much finer, steady and easy to be controlled with a relatively better ordered structure. And the conductivity of the films is higher than that of ODA/PEDOT-PSS films and there observed anisotropy conductivity on both LB films： The gap between horizontal conductivity （σⅡ） and vertical conductivity （σ⊥） of the films is as high as 3 to 4 quantitatively. Exponential characteristics of Ⅰ-Ⅴcurves of above LB films were observed and it can be ascribed to typical electron tunneling in multilayer structures.
