摘　　要：利用两种溶胶-凝胶工艺制备了TiO_2粉体,并对TiO_2表面进行有机改性。结果表明:Ⅰ号工艺更好,在实验范围内,适宜的有机改性条件为:改性剂为月桂酸钠,改性时间为30 min、改性温度为40℃、有机改性剂的用量为10%、在环己烷中的亲油化度值为0.61 g。In this paper,TiO2 powders were prepared by two different sol-gel methods and were modified by organic modifier.The results show that TiO2 powders prepared by the first sol-gel process is better than the second one.The optimum conditions for the modification of TiO2 powders are as follows：the organic modifier is sodium laurate,modification time is 30 min,modification temperature is 40 ℃,the amount of sodium laurate is 10%.Under these conditions,the degree of lipophilicity in cyclohexane is 0.61 g.
