摘　　要：分析了纳米颗粒团聚形成的原因,阐述了研究纳米颗粒分散的意义,着重介绍了物理分散和化学分散技术研究进展,指出纳米颗粒分散技术的发展方向是设计高效分散机械,以提高有效分散体积和能量利用率;合成性能优异的超分散剂及研究不同的混合分散剂,以提高分散后的粒子稳定性,最终提高分散效果;加强纳米颗粒分散的基础理论研究及其与其他学科融合交叉,为纳米颗粒分散及分散剂的选择提供理论指导,并开发新的适合纳米材料制备的新工艺。The causes of agglomeration in nano - particles were analyzed and the significations of dispersion of nano - particles were expounded. Present research status and development on technique of dispersion using chemical or physics methods are reviewed. The main development trend of dispersion technique for nano- particles is to design effective disperse machines, which to enhance the volume of dispersion on nano- particles and using rate of energy; synthesis some excelled dispersants and research on different mixdispersants, which to enhance the stability of dispersed nano-particles and the finally disperse effect; make more further studies on basic theories of dispersion on nano - particles and the interject with other subjects, of which the purpose is to give some direction on the dispersion of nano - particles and the select of different dispersants, and exploit some newly techniques fitting nano - particle materials.
