通过复制由直径35纳米的二氧化硅微球制成的胶体晶体，制备了有序介孔聚合物。胶体晶体中的孔被二乙烯基苯(DVB)、乙二醇二甲基丙烯酸酯(EDMA)或两者的混合物填充。二氧化硅模板的聚合和随后的溶解留下了相互连接的孔的多晶网络。当使用DVB和EDMA的混合物时，聚合物复制品的孔径可以在35到15纳米之间连续变化，因为当去除二氧化硅模板时，聚合物会收缩。
Ordered mesoporous polymers have been prepared by replication of colloidal crystals made from silica spheres 35 nanometers in diameter. The pores in the colloidal crystals were filled with divinylbenzene (DVB), ethyleneglycol dimethacrylate (EDMA), or a mixture of the two. Polymerization and subsequent dissolution of the silica template Leaves a polycrystalline network of interconnected pores. When mixtures of DVB and EDMA are used, the pore size of the polymer replicas can be varied continuously between 35 and 15 nanometers because the polymer shrinks when the silica template is removed.
