聚合物包覆改性纳米二氧化钛的研究进展

Progress on surface modification of polymer encapsulated nano-TiO_2

综述了近年来国内外采用聚合物包覆法对纳米二氧化钛进行表面改性的研究工作,主要从改性原理和制备工艺的角度对聚合物包覆改性纳米二氧化钛的方法进行了分类阐述。对表面接枝法、微胶囊法和锚定位包覆法、原位聚合法、后处理改性法以及一些物理方法进行了举例介绍和比较。最后提出了目前聚合物包覆法改性纳米二氧化钛存在的问题和发展方向等。

The research work of recent years on surface modification of polymer encapsulated nano- TiO2 in China and the world were reviewed. The principles and methods of surface modification of polymer encapsulated nano- TiO2 were mainly described systematically. Examples for some methods such as the method of graft polymerization from surface, the microencapsulation method, the anchor wrapping method, the in - situ polymerization method, the post treatment method and some physical methods were provided and comparisons were made. Issues and developing trend in this field were discussed.
