摘　　要：胶态晶体中的粒子一般具有蛋白石结构，通过胶态晶体空穴可以制备反蛋白石结构的多孔材料，孔径可由100nm以内到1000nm不等，并具有三维长程有序的孔结构，可望应用于光学器件、光子晶体、催化剂、特殊过滤膜及其它领域。重点介绍了胶态晶体模板法在多孔材料合成上的应用及其未来的发展前景。Commonly the colloidal crystals are of opal structures. It is possible to synthesize porous materials of inverse opal structures by making use of colloidal crystals＇void space. Their pore radius varies from less than lOOnm to 1000nm, and these materials have the three-dimensional, long-ranged ordering pore structure. They are expected to have the applications such as photonic devices, photonic crystals, catalysts, and special filter membranes, and many other fields. This paper casts light on the colloidal crystal template methods used in the formation of these materials and likely future trends in the field.
