摘　　要：片状纳米银粉的化学制备技术备受人们关注。本文综述了片状纳米银粉的化学还原沉淀法、软模板法、电化学沉积法、热沉积法等化学制备技术,探讨了化学法制备片状纳米银粉的形成机理。片状纳米银粉由于表面效应和量子尺寸效应表现出独特的光、热、电、磁、催化等性能,在导电、杀菌、催化、生物等方面得到广泛的应用。片状纳米银粉的化学制备技术显示出诱人的发展前景。The chemical preparation technique of silver nanoflakes has attracted comprehensive attention and research. The chemical preparation technique of silver nanoflakes can be summarized in four categories. chemical reduction aggradation, soft template, electrochemical deposition and annealing deposition. The formation mechanism of silver nanoflakes prepared by the chemical preparation technique is especially discussed. Silver nanoflakes exhibit unique chemical and physical properties, including optical, thermal, electronic, magnetic and catalytic properties due to surface and quantum size effects. Silver nanoflakes have extensively been applied to conducting electricity, bactericidal, catalysis and biological field. The chemical preparation technique of silver nanoflakes has shown attractive potential in development.
