采用原位聚合法制备了介孔材料/不饱和聚酯(SBA-15/UP)复合树脂，通过X射线衍射（XRD）、氮气吸附-脱附、热重分析（TGA）等表征了SBA-15及SBA-15/UP的相关性能，研究了不同SBA-15含量对SBA-15/UP热性能及电性能的影响。结果表明：在原位聚合过程中，SBA-15的有序性降低，其孔径由原来的6.64 nm下降到0.926 nm，表明UP分子链嵌入到SBA-15孔道内形成了有机-无机互穿网络结构；与纯UP相比，添加1%~3%的SBA-15后，SBA-15/UP复合树脂的热稳定性明显提高，其Td5%较纯UP的Td5%均提高了25℃左右。

A mesoporous material/unsaturated polyester(SBA-15/UP) composite resin was prepared through in-situ polymerization. The properties of SBA-15 and SBA-15/UP were characterized by X-ray diffraction (XRD), nitrogen adsorption-desorption, thermogravimetric analysis(TGA), and the effects of SBA-15 con-tent on the thermal properties and electrical properties of SBA-15/UP were studied. The results show that the ordering of SBA-15 decreases during the process of in-situ polymerization, and the diameter of SBA-15 reduces from 6.64 nm to 0.926 nm, which indicate that the UP molecular chain is embedded in the pore channel of SBA-15 and forms a organic-inorganic interpenetrating network structure. Compared with the pure UP, when the SBA-15 content is 1%~3%, the thermal properties of the SBA-15/UP compos-ite resin increases obviously, and the Td5% increases by 25℃.
