摘要：

采用胶体化学法制备了稳定的SnO2纳米粒子（nanoparticle NP）水溶胶，用膜天平和原位布儒斯特角显微镜（BAM）考察了经典成膜材料花生酸（AA）在此水溶胶气-液界面的成膜性，并用LB膜技术在不同基底上制得了单层和多层AA-SnO2 NP复合LB膜，通过TEM、小角X-ray、IR和UV-VIS光谱，进一步考察了该有序组装体的结构和周期性，以及组装作中SnO2纳米粒子的形貌、粒度分布和表面聚集状态. 结果表明，用这种方法能够制得粒度分布均匀、农致密的SnO2纳米粒子复合LB膜，并且多层复合膜具有良好的周期性.

Abstract:

The hydrosol of SnO2 nanoparticles (NP) have been prepared by colloid chemistry method. The composite LB monolayer and multilayer of SnO2 NP-AA have been obtained by LB technique at the gas-liquid interface of the hydrosol subphase. The structures of the monolayer and multilayer were characterized by IR, UV-Vis, small angle X-ray diffraction spectroscopy and TEM technique. The results indicate that the coverage of SnO2 NP at the composite monolayer's surface is high and the sizes of SnO2 NP are similar. The multilayer has good periodic structure.
