摘要
片状银颗粒具有独特的电性能、光性能等优良性能,近年来,在各个领域引起了广泛的关注。液相化学还原法具有反应条件可控、利于量产的优势,被广泛用于片状银颗粒的制备中。本文首先介绍了在液相化学还原法中片状纳米银颗粒的生长机理,分析了各反应条件,例如pH值、晶种、表面活性剂、硝酸银浓度等对生成片状银颗粒的影响。综述了国内外利用液相化学还原法制备片状银颗粒的研究进展;针对研究中存在的一些问题,展望了下一步的研究方向。
Flake silver particle has attracted tremendous interest due to its specially electrical and optical properties. Solution chemical reduction method with the advantages of reaction conditions easily controlled and mass production is widely used to prepare flake silver particles. In this paper, the growth mechanism of flake silver particles was introduced in the solution chemical reduction method. The impacts of reaction conditions, such as pH value, kinds of silver seeds, kind of surfactant and concentration of silver nitrate, on growth of flake silver particles was analysed. And research development of preparing flake silver particles by solution chemical reduction method was reviewed at home and abroad. Future research directions were looked forward to solve some problems existing in the preparation of flake silver particles.
