| 摘 要： | 本文采用原位合成法合成了富含羧基的SBA-15球形介孔分子筛. 研究了修饰剂（三烷氧基氰乙基硅烷 CTES）的用量对介孔分子筛SBA-15形貌、孔径及BET比表面积的影响. 用粉末X射线衍射(XRD)、扫描电镜(SEM)、红外（IR）和氮气吸附/脱附对样品进行了详细的表征. 该材料展示了尺寸在0.5-1 μm规则的球形形貌、有序的二维六方相介孔结构、较大的比表面积和孔容、并且随着修饰剂用量的增加, SBA-15的孔径变小, 比表面积下降. 药物组装及缓释性能测试表明, 该材料具有较好的药物组装及缓释释放性能. 该材料在催化、药物载体和色谱分析填料等领域将具有潜在的应用.

| Abstract: | Mesoporous SBA-15 spheres with abundant carboxyl were synthesized by a one-step method.The effects of CTES amount on the morphology,pore size and BET surface area of mesoporous SBA-15 were investigated.The samples were characterized by powder X-ray diffraction(XRD),scanning electron microscopy(SEM),infrared(IR) spectra and nitrogen adsorption/desorption techniques.The morphologies of as-obtained products are sphere-like.The materials possess highly ordered hexagonal mesoporous structure,large specific surfa... |
