纳米粉体由于其具有特殊的性能而被广泛应用,但纳米粉体的团聚一直是困扰纳米材料制备和应用的关键问题,表面改性是有效解决这一问题的方法。本文介绍了目前纳米粉体表面改性方法及改性基本原理。对化学改性、高能量辐照改性和机械研磨改性进行了阐述。
Nano-powders have been widely used because of their special properties. However, the agglomeration of nano-powders has always been a key problem that plagues the preparation and application of nano-materials. Surface modification is an effective way to solve this problem. This paper introduces the current nano-powder surface modification methods and modification of the basic principles. Chemical modification, high energy radiation modification and mechanical grinding modification are described.
