纳米银石墨烯的制备及其疏水性能的研究

Preparation and Hydrophobic Property of Silver Nanoparticle-Graphene Composites

概述了纳米银石墨烯(AgNPs-rGO)的制备方法,通过抗坏血酸还原并加入PVP减少纳米银粒子的团聚得到纳米银石墨烯(AgNPs-rGO)复合材料,然后用SEM和FTIR对纳米银石墨烯复合材料进行了表征,采用微观接触角测量仪研究了纳米银石墨烯复合材料的疏水性能。结果表明:当AgNO3:GO质量比为2:1时,制得的AgNPs-rGO复合材料的水接触角为36˚,在此复合材料中有最优的疏水性能。

The preparation methods of silver nanoparticle-graphene composites (AgNPs-rGO) were summa-rized and a series of AgNPs-rGO were obtained by ascorbic acid reduction. The obtained AgNPs-rGO composite materials were subsequently analyzed by SEM and FTIR spectroscopy and their hydro-phobic properties were characterized by using a micro contact angle measuring instrument. The results show that when the mass ratio of AgNO3 and GO is 2:1, the water contact angle of AgNPs-rGO composite material is about 36˚ and this corresponding composite has the best hydrophobic prop-erty.
