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.
