| 摘 要： | 对纳米二氧化钛进行表面改性处理是钛白粉工业生产中必不可少的关键步骤，处理的方法和包覆的程度直接影响产品的应用范围。阐述了纳米二氧化钛的表面改性原理和化学表面改性的两种方法——无机包膜改性和有机包膜改性。无机包膜改性包括铝包膜改性、硅包膜改性、铁包膜改性和硅铝复合包膜改性；有机包膜改性主要是醇类化合物和羧酸类化合物对纳米二氧化钛的包覆改性。

| Abstract: | Surface modification of nano-sized titania is one of the key steps in commercial production of titania and it can directly effecte the application fields of titania powder. The principles of modification of nanoscale titania were introduced in this article. Coating a film of organic or inorganic compound on its surface which is two means of surface modification is reviewd in the paper. Inorganic surface modification includes surface modification with Aluminium, surface modification with silicon surface modification with iron and composite surface modification with silicon and aluminium. Organic surface modifications were mainly interpreted by the alcohol compounds and carboxylic acid compounds coating on the surface of titania. |
