摘　　要：将制备介孔材料的传统方法与超临界流体方法进行了比较, 总结了超临界流体技术在介孔材料制备中用于清除模板剂以及作为载体使硅基基团渗透入介孔模板两方面的应用, 并介绍了以高聚物为模板制备介孔膜的原理。以超临界流体方法制备介孔材料, 所得的产品孔径分布更窄, 材料结构更规整、更有序, 且模板清除率和硅基的装载效率都得到了提高。The researches on supercritical fluid technology in the field of materials, especially in the production of mesoporous materials have been rapidly increasing. A comparison was made between the traditional and supercritical fluid methods on the production of mesoporous materials. The application of the latter to extracting surfactant template and impregnating the functional materials such as silicon into the template is discussed. The principles of making mesoporous membrane with the polymer as template are presented. The products made with supercritical fluid technology are much more regular and ordered. Both the extraction rate of the template and the silicon loading rate are increased.
