简单介绍了传统的对纳米粉体表面改性的方法,同时在实验的基础上自行发展的一种新的利用低温等离子体对纳米材料表面引发接枝聚合改性的方法,通过红外(FT-IR)、X射线光电子能谱(XPS)以及热失重分析(TGA)测试表明该聚合膜是通过化学键连接在纳米粉体表面的,X射线衍射光谱(XRD)表明经等离子体处理改性的纳米粉体只是其表面性质发生了改变,其晶体结构并没有发生任何变化。 A brief introduction of the traditional methods for surface modification of nano-sized powders and a new method of modifying the surface of nano-sized nano-materials using low temperature plasma developed on the basis of experiments were introduced. The FT- IR, XPS and TGA results show that the polymer film is chemically bonded to the surface of the nanopowders. X-ray diffraction (XRD) shows that the nanoparticles are modified by plasma treatment Powder only changes its surface properties, its crystal structure has not changed.
