三维有序大孔材料的合成及应用

胶晶模板法是制备三维有序大孔(3DOM)材料较理想的方法,制备过程一般包括组装胶晶模板、往模板间隙内填充前驱物和去掉模板及前驱物转化等3个步骤。每一步都对产物的三维有序大孔结构有很大的影响。这种材料兼具固体材料本身和有序结构两种特性,在用作光子晶体、载体、电极材料、气敏元件和分离材料等方面具有潜在应用性。本文着重介绍了大孔材料的合成及应用。

Preparation and Application of Macroporous Materials

Colloidal crystal templating method is a promising method to fabricate three-dimensional ordered macroporous(3DOM) materials.The method usually involves three steps,namely,assembly of template from uniform monodispersed beads, deposition of desired precursor inside the template and finally removal of the template.Each step has significant effect on the structure formation of the 3DOM materials.Such 3DOM materials hold the merits of both functional character of solid materials and ordered macroporous structure.They have potential applications in the fields such as photonic crystals,catalysts,supports,sensors,and battery materials et al.In this paper,the strategies for fabrication of 3DOM materialsby colloidal crystal templating method and applications of 3DOM materials are briefly reviewed.
