摘　　要：纳米TiO2 的表面处理的好坏直接影响到产品的应用性能及其使用范围。目前的处理措施主要是在其表面上包覆一层无机或有机物膜 ,以避免粉末间的团聚。从表面包覆的原理、影响因素、包覆方法以及表面包覆效果的表征方法等方面概述了纳米TiO2 颗粒包覆的研究进展 ,着重介绍了纳米TiO2 无机、有机包覆的原理及近年来的研究成果 ,并提出今后的研究方向。Quality of surface modification of nano-TiO 2 has directly effect on its application behavior and domain. Coating a film of organic or inorganic compound on its surface to avoid the aggregation of the particles is adopted frequently. Advanced of coated nano-TiO 2 were reviewed, including principle of coating ,influence factors ,ways of coating and testing measures of coating result .The principles of inorganically coated nano-TiO 2,organically coated nano-TiO 2 and research results in recently years were introducted on emphasis .Ways of research in the future were proposed .
