中文摘要：

通过烯丙基环糊精（ally1-β-CD）与丙烯酸（AA）的共聚合反应在环糊精聚合物链中引入了活性基团羧基,运用溶胶-凝胶法制备了新型的环糊精聚合物P（CD-co-AA）/TiO2有机-无机杂化材料.溶剂抽提结果和FT-IR表明杂化材料中有机无机两相间存在着化学键.通过XRD,SEM,TGA研究表明有机无机两相高度相容,热稳定性能有大大的提高.另外还发现,在所制的材料中TiO2的含量对材料的结构和性能有很大的影响,当TiO2的含量为60%（w）时,材料表面均匀光滑,有机无机两相相容性和材料的热稳定性能最好.

英文摘要：

Inorganic-organic hybrid materials of P（CD-co-AA）/TiO2 were prepared by sol-gel process, and in order to introduce the chemical bond between the organic polymer chain and inorganic network of the hybrid, the carboxyl functional group was introduced into polymer side chain by copolymerization between allyl-fl-CD and acrylic acid （AA）. The results of solvent extraction and FT-IR show that there is the chemi- cal bond between the TiO2 phase and the polymer matrix of the hybrids. The hybrid materials were charac- terized by XRD, SEM and TGA, while the results indicate that the TiO2 phase and polymer matrix were well dispersed evenly with each other. At the same time, it was found that the TiO2 content influenced the struc- ture and properties of the hybrid materials. The hybrid materials acquired more excellent thermal stability and the intermolecular regularity when the content of TiO2 in the hybrid was 60% （w）.
