摘　　要：在油酸钠保护下用NaBH4 还原AgNO3 ,制得了银纳米粒子胶体溶液 .利用相转移剂NaH2 PO4 等 ,使Ag纳米粒子在水 /有机相界面之间形成薄膜 .形成的Ag纳米粒子膜可以转移到玻璃等基质上 ,讨论了其转移机理 ;并用石英晶体微天平 (QCM)定量检测了银纳米粒子的相转移量 .Ag nanoparticles were produced by the reduction of AgNO3 with the protecting of sodium oleate using NaBH4. After adding, the transferring regent NaH2PO4, a film of Ag nanoparticles was formed at the interface of water/organic phase. The film could be transferred to a substrate such as glass. The mechanism of the transfer of the film was discussed. Quartz Crystal Microbalance (QCM) was also used to measure the transferred colloidal quantity for Ag nanoparticles.
