摘要/Abstract

摘要： 利用Langmuir-Blodgett (LB)方法, 以二十二酸 (behenic acid, BA)、二十酸(arachic acid, AA)、十八酸 (stearic acid, SA) 和十八胺 (octadecanyl amine, OA)作为辅助成膜材料, 组装了C₆₀复合膜和BA膜, 液下原子力显微镜直接对LB膜在水相中的重组进行观察. 结果表明, C₆₀复合LB膜和二十二酸镉单层膜在水相中都发生了重组, 但前者的重组程度较小，并且C₆₀聚集体颗粒的粒径均匀. 脂链的重组可能是由于水相中的Cd²⁺减弱了头基与云母基片之间的相互作用引起的, 相同条件下由于混合C₆₀膜中发生酸碱缔合使其重组程度较小.

关键词: BA和C₆₀复合LB膜, 重组, 原子力显微镜

Abstract: The assemblies of the C₆₀ mixed film and the behenic acid (BA) film were made successfully by means of Langmuir-Blodgett (LB) technique with BA, arachic acid (AA), stearic acid (SA) and octadecanyl amine (OA) as the assistant material, and the reorganization of the LB films was directly observed by liquid atomic force microscopy (AFM). The AFM data show that the C₆₀ mixed film and the BA film were all reorganized in water with the uniform size of C₆₀ aggregates, and the weaker reorganization was observed for the former. It is considered that the Cd²⁺ in water decreased the interaction resulted in the reorganization of alkyl chains between headgroups and the mica substrate. Owing to the reaction of the acid and alkali, the C₆₀ mixed film got weaker reorganization in water compared with the cadmium behenic films.

Key words: BA and C₆₀ composite LB films, reorganization, atomic force microscopy
