At the same time, the fouling mechanism of membranes given in this thesis can give a reasonable explanation on the change of membrane performance. Our results show that the magnetization of membranes can effectively improve the anti-fouling ability of the PAN- Fe_3O_4 membrane. The obtained result may give insight to the development of new membranes with a good anti-fouling performance in the filtration of blood solution. No chemical bond was found between PAN and Fe_3O_4 in the membrane at room temperature. The addition of Fe_3O_4 can improve the temperatures of dehydrogenated reaction and decomposition of PAN but dot change the glassy transition temperature. The resistance against acid is stronger than the resistance to base for a PAN- Fe_3O_4 membrane.

结果表明在PAN- Fe_3O_4超滤膜制备过程中使用外加磁场作用能有效提高膜的耐污染能力，这一结果为开发适用于血液处理的耐污染超滤膜提供了一种新途径；在PAN- Fe_3O_4超滤膜中，四氧化三铁与PAN在室温下没有形成化学键，也不存在官能团之间的相互作用；添加Fe_3O_4对膜的玻璃化温度没有影响，但能提高PAN环化脱氢反应的温度和分解温度；PAN- Fe_3O_4超滤膜的耐酸性强于耐碱性，在pH值为10以上的溶液中由于水解作用而溶解，使得膜失去使用价值，膜的耐酸性与酸的种类、浓度和氧化性有关。

In the Aldol condensation of acetone with 4-nitrobenzaldehyde, two different hybrid secondary amine-functionalized mesoporous materials displayed enhanced catalytic performance in comparison to primary amine-functionalized materials. The possible reason is that the presence of organic functional groups with larger steric hindrance led to the enhanced catalytic performance of basic amino groups.

在对硝基苯甲醛和丙酮的羟醛缩合反应中，相对于一级胺功能化的材料，二级胺功能化的SBA-15展示了极大改进的催化活性，这可能是由于具有更大空间位阻效应的有机功能团的引人导致了碱性胺中心催化活性增强。
