液/液界面反应法合成金纳米颗粒膜

摘要

The process and conditions to form ultrathin Au nanoparticle films by liquid/liquid interfacial reaction (LLJR) were investigated by in -situ optical microscopy, contact angle measurement and UV -Vis analysis, assisted with ex - situ characterizations by SEM, AFM ,TEM and XRD. The effects of different reducing agents and organic solvents on the morphology of Au deposits at the liquid/liquid interface were studied, which indicate that toluene and THPC are of substantial importance for the preparation of Au nanoparticle films by LLJR. The interfacial reaction and the cleavage of reactants Au(PPh3)Cl and THPC were preliminary discussed.%通过光学显微镜、接触角与紫外可见光谱分析、扫描电镜、原子力显微镜、透射电镜和X光衍射分析等手段,分析了液/液界面反应生成金纳米颗粒膜的过程和形成条件,研究了不同还原剂和有机溶剂等对界面产物形貌的影响,结果表明甲苯和THPC的使用对制备金纳米晶颗粒膜具有重要作用,同时还对反应物Au( PPh3)Cl和THPC的分解与界面反应过程进行了初步讨论.
