毕业论文CTAB与P123共同合成介孔硅的制备及其负载姓名院（系）化学化工学院专业班级学号指导教师职称/职务论文答辩日期2019年5月18日摘要在本篇论文中，主要将模板剂设定为三嵌段表面活性剂P123及其相应的CTAB。与此同时，硅源领域所涉及的专业用语（法律条文等）主要选择正硅酸乙酯（英文简称TE0S),此外还借助水热法成功获得已经改性后的介孔硅材料。通过改变CTAB与P123的不同配比，制备出多组介孔硅材料，并与于相同条件下制备的介孔MCM材料对比，研究其孔道结构和表面形状及其载药性能的变化，来探究双模版剂制备介孔硅材料到一般规律。不仅如此，本文还选择扫描电子显微镜（英文简称SEM)以及N2吸附-脱附法(BET)对所制备产物进行表征，得出混合模板剂改性介孔硅最大载药量为2.2%，最优配比为CTAB:P123=1:4。关键词：介孔硅材料双模板剂合成水热法载药性能AbstractIn this paper,the templating agent is mainly set to the triblock surfactant P123 and itscorresponding CTAB.At the same time,the professional terms (legal provisions,etc.)involvedin the field of silicon source mainly choose ethyl orthosilicate (TEOS),and the mesoporoussilicon material has been successfully obtained by hydrothermal method.By changing thedifferent ratios of CTAB and P123,a plurality of mesoporous silicon materials were preparedand compared with mesoporous MCM materials prepared under the same conditions.Thechanges in pore structure,surface shape and drug-loading properties were investigated.Thetwo-mode version prepares the mesoporous silicon material to the general rule.Not only that,but also the scanning electron microscopy (SEM)and N2 adsorption-desorption method(BET)were used to characterize the prepared product,and the maximum drug loading of themesoporous silica modified by the mixed template was 2.2%.The ratio of the ratio is CTAB:P123=1:4.Keywords:Mesoporous silicon material Double template synthesis hydrothermal processDelivery performance
