摘　　要：本文制备了Ａｇ２Ｏ胶体粒子的自组装单层膜和多层膜。运用接触角测量、红外吸收光谱和紫外可见吸收光谱等手段证实了Ａｇ２Ｏ胶体粒子能够组装在具有羧基的基底上，在有１。In this study, we report on the self assembly (SA) behavior of silver oxide colloids on carboxylated substrates. UV visible spectra demonstrate that they can form SA multilayers by using crosslinker such as octadecanedioic acid (ODDA). FTIR spectrum of the SA system shows that part of ODDA molecules reacts with Ag 2O molecules to form fatty acid salt. The contact angles of water on the SA systems vary with the different substances on the surface.
