Ordered mesoporous carbons (OMCs) with an intergrown two-dimensional p6mm and three-dimensional Fd3m pore structure have been prepared by the carbonization of reverse copolymer-phenolic resin composites, which were themselves formed by a soft-template method by simply adjusting the ratios of ethanol and hexane. The microstructure of the OMCs was analyzed by small-angle X-ray scattering, nitrogen adsorption isotherms, and transmission electron microscopy. The results showed the structure of the OMCs obtained have the mesophase transition from p6mm to the intergrowth of p6mm/Fd3m and finally to Fd3m as the ratio of ethanol to hexane is changed.
有序介孔碳（OMC）具有二维 p6mm 和三维 Fd3m 共生的孔结构，通过碳化反共聚-酚醛树脂复合材料制备而成，而复合材料本身则通过简单调整乙醇和正己烷的比例，采用软模板法形成。通过小角 X 射线散射、氮气吸附等温线和透射电子显微镜对 OMCs 的微观结构进行了分析。结果表明，随着乙醇与正己烷比例的变化，所得到的 OMCs 的结构经历了从 p6mm 相向 p6mm/Fd3m 共生相再到 Fd3m 相的介晶转变。
