摘要
三维有序大孔材料具有整齐有序的孔道、分布均一的孔形孔径,因而在催化剂载体、过滤和分离材料、电极材料以及热阻材料等有着非常重要的作用。模板法是制备三维有序大孔(3DOM)材料最常用的方法。其制备过程包括模板的制备、组装,往模板微球间的间隙填充前驱物溶液及模板的去除这几个步骤。结合近年来对这方面材料的研究工作及文献作一简要系统的综述。
Three-dimensionally ordered macroporous materials are successfully synthesized through using latex sphere colloid crystals as template. This paper reviews the strategies for the synthesis of 3DOM by colloidal crystal templating method. The method mainly involves several steps, including fabrication of template from monodispersed colloidal sphere, assembly of colloidal crystal templating, deposition of desired precursor inside the templateand removal of the template.
