摘要
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。
Nanoparticles are widely used due to their unique properties,but the agglomeration of nano-powder plagued preparation and application of nano-materials,and surface modification is an effective solution to this problem.This article describes the methods and basic principles surface of modification of nano powder.Chemical modification,high-energy irradiation and mechanical polishing modification are described.
