摘　　要：采用超声波分散技术,通过原位合成法将pH敏感的功能单体甲基丙烯酸(MAA)引入到介孔二氧化硅SBA-15的孔道内聚合,制备了pH敏感SBA-15/聚甲基丙烯酸(PMAA)纳米复合材料,对材料的结构和性能进行了测试。结果表明,介孔分子筛SBA-15/PMAA复合材料有较好的光学性能、热性能。聚合反应的发生并没有破坏SBA-15的有序介孔结构,显示出pH敏感性,有望在药物缓释领域得到应用。The pH-sensitive functional monomer methacrylic acid （ MAA ） was introduced into the pores of mesoporous silica SBA-15 for polymerization by the method of situ synthesis. The results show that the mesoporous SBA-15/PMAA composite materials have good optical properties and thermal properties com- pared with the pure PMAA. The polymerization reactions did not destroy the mesoporous structure of SBA-15 ,such nanocomposites initially showed a pH sensitivity. This pH-sensitive mesoporous nanocom- posite which has a higher specific surface area than others is expected to be applied in the field of drug delivery.
