摘要
对用电解法制备的纳米金红石型二氧化钛粉体进行了表面改性研究 ,分别采用硬脂酸钠和聚乙二醇改性剂 .实验研究了改性剂用量、浓度及改性时间对粉体表面的影响 ,结果表明 ,控制适当的改性剂用量及浓度和时间 ,可获得较好的表面改性效果 。
Surface modification of TiO 2 with rutile type is investigated. The TiO 2 is obtained by electrochemical synthesis. The sodium stearate and polyethelene glycol are served as the modification reagent. The effect of the reagent amount, concentration and the synthesis time to the modification are determined. The results show that it can achieve better modification effects by controlling the amounts and concentration. The modification mechanism of the nanosized titanium dioxide powder is analyzed.
