纳米银是亲水还是疏水

疏水

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。

什么样的电镜都不能直接观察水溶液内部的物质。

您需要把物质从溶液中提取出来，然后观察，提取可以是蒸馏，也可以是使用TEM用的微栅网来捞纳米粒子。然后采用扫描电镜或者透射电镜观察。粒子的成分可以用能谱仪EDS来确认。

The proper control of nanostructured silver’s morphology was achieved by using silver nitrate as raw material and modifying the quality of polyvinylpyrrolidone (PVP)and through the application of polyol synthesis, various morphologies of nanostructured silver were produced, mainly in the form of nano-wire and nano-particles. Discussion was focused on the impact of PVP on the morphology of nanostructured silver, and its growth mechanism was investigated by conducting characterization on the samples by using various testing techniques such as XRD,SEM,UV-VIS, etc.
