| 摘 要： | 用溶胶凝胶法制备了二氧化钛(TiO2)纳米粒子,并用硅烷偶联剂γ-甲基丙烯酰氧基丙基三甲氧基硅烷(γ-MPS)对其表面进行改性,继而采用光引发自由基聚合制备了聚(N-异丙基丙烯酰胺-co-丙烯酸)/TiO2复合微球。考察了共聚单体丙烯酸(AA)、表面活性剂司盘80(Span80)在反应体系中的加入量对制备微球的影响,并比较了不同干燥方法对微球形态的影响。结果表明:合适的单体加入量、表面活性剂用量以及干燥方法可制备出分散性和球形度较好的复合微球。

| Abstract: | TiO2 nanoparticles were prepared by sol-gel method and modified with γ-MPS.Poly（NIPAM-co-AA）/TiO2 was prepared via UV-initiated radical polymerization.The effects of AA and Span80 contents,and different drying methods were investigated.The results demonstrated that the content of the co-monomer,the concentration of the surfactant and the drying method played significant roles in the preparation of the microspheres. |
