摘　　要：利用廉价的油酸对纳米二氧化钛(TiO2)表面处理后,采用原位聚合法制备了聚丙烯酸酯包覆纳米TiO2复合乳液。通过FT-IR、TGA、亲水亲油性对比实验等表征手段证明纳米TiO2表面已成功被油酸修饰,TEM照片显示改性改变纳米TiO2被聚丙烯酸酯包覆,并且讨论了纳米TiO2的加入量对单体转化率、乳胶粒粒径及乳胶膜耐水性的影响。The low cost oleic acid was used to modify the TiO2 nanoparticles, which wrer then coated with polyacrylate by insitu polymerization. The characterization results, such as FT-IR, TGA and the hydrophilic lipophilic contrast tests, proved that the surface of TiO2 nanoparticls was successfully modified with oleic acid, the TEM photographs showed that the modified TiO2 nanoparticles were successfully coated with polyacrylate, and the effect of addition amount of TiO2 nanoparticls on the monomer conversion, particle size and water resistance of the latex was discussed.
