有序介孔有机硅杂化材料的制备研究

The synthesis of periodic organosilica mesoporous

分别采用两种不同的模板剂在不同的酸碱条件下成功地制备出有序介孔有机硅杂化材料,通过X射线衍射图谱、热失重分析和透射电子显微镜对制备的材料进行了表征,结果表明以嵌段共聚物和阳离子表面活性剂为模板剂均能成功制备出有序的介孔材料,而且所制得的材料具有优良的热稳定性,不同的有机官能团的引入大大地丰富了介孔材料的种类和用途。

Periodic organosilica mesoporous were successfully prepared using two different templates under different pH conditions. The XRD, TGA and TEM characterazation illustrated that both the triblock copolymer and the cation surfactant can be used as the templates for structure directing in the synthesis of periodic organosilica mesoporous, in addition the POMs had strong stability during heating process. New mesoporous silicas with different organic functional groups can enlarge the types and applications of the periodic organosilica mesoporous family.
