中文摘要：
采用湿化学法制备了系列贵金属纳米颗粒（Ag、Au、Pt和Rh），并通过相转移过程实现了贵金属纳米颗粒的自组装，首先将水相中制备的贵金属溶胶与十二胺的乙醇溶液混合，然后将十二胺稳定的金属颗粒从极性的水相中转移到非极性的有机相中。这种方法不仅能实现金属纳米颗粒在基底上的自组装，而且有望应用于纳米颗粒自组装膜的制备中。
英文摘要：
Taking wet-chemistry method to prepare a seiries of noble metal nanopartMes（Ag,Au,Pt a,d Rh ）, and achieve the self-assembly of noble metal nannoparticles by phase transfer process, First, mixing the metal hydrosol with tile ethanol solution of alkylamine, Then taking dodecylamine stable metal particles from the polar aqueous phase to the nonpolar organic phase.This method not only offers an effective approach to self-assembling of metal nanoparticles on the substrate, but also can be expected to used in the preparation of self-assembled nanopartiele layers.
