在纳米粉体的研究和应用过程中，如何得到高度分散的纳米粉体是一难题。采用均匀沉淀法合成纳米ZnO，讨论了其在非水介质中的分散条件及其影响因素。通过阴离子表面活性剂包覆纳米ZnO，可以得到其在非水介质中的分散体系。经IR和TEM检测，表明包覆层均匀，颗粒粒径介于30～80nm。

Preparation of highly dispersed nanometer dispersion has been a key solution during the study and application of nanometer powders. A nanometer ZnO powder has been prepared by uniform precipitation process. The conditions and influencing factors for its dispersing in non - aqueous system are discussed. A non- aqueous dispersion has been obtained by use of anionic surfactant coated ZnO, which shows an uniform coating and 30 ～ 80 nm particle size by IR and TEM analyzing.
