Abstract:Ag nanoparticles were produced by the reduction of AgNO 3 with the protecting of sodium oleate using NaBH 4. After adding the transferring regent NaH 2PO 4, 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.
Keywords:Ag nanoparticles  monolayer film  phase transfer  QCM
