Effects of the Ratio of Surface Protective Agent on the Preparation of Nano-silver

摘要

It has many advantages with liquid phase reduction method to prepare the nano-silver,such as experimental conditions are simple,low cost,energy-saving,etc..At the same time,the nano silver powder prepared by this method has high surface activity,catalytic property and wide usage.In this paper,nano-silver powder was prepared by changing the amount of protective agents with chemical liquid phase reduction method.This paper focuses on the impact of the amount of protective agent on the nano-silver.In addition,we also analyzed the reaction temperature,PH value of solution,viscosity and electrical conductivity on the preparation ofnano-silver.Finally,test results from the TEM shows that the nano-silver was prepared with smaller size,uniform size and good dispersion.
