A soft-phase intercalating process to synthesize mesostructured plasticine by using amphiphilic triblock copolymer F127 as a structure-directing agent, reverse triblock copolymer 25R4 as an intercalating soft matter, and soluble phenolic resin as a carbon source is demonstrated. The "plasticine" has interlayer organic-organic hybrid structure, which is emplastic, sticky, and able to be easily shaped at will. After template removal at 350 degrees C and further carbonization at 600 degrees C, highly ordered mesoporous polymers and carbons can be successively obtained with the maintenance of the original shape. The self-supported, shape-controlled, ordered mesoporous carbon products possess high surface areas (495-777 m(2)/g), large pore volumes (0.32-0.47 cm(3)/g), uniform pore sizes (2.5-4.3 nm) in the nanoscale and hollow tremella-like morphology in the micronscale which may facilitate mass transportation.
展示了一种软相插层工艺，该工艺以两亲性三嵌段共聚物F127作为结构导向剂、反向三嵌段共聚物25R4作为插层软物质、可溶性酚醛树脂作为碳源来合成介孔橡皮泥。这种“橡皮泥”具有层间有机-有机杂化结构，具有可塑性、粘性且易于随意塑形。在350℃去除模板并在600℃进一步碳化后，可以依次获得高度有序的介孔聚合物和碳，同时保持原始形状。这种自支撑、形状可控的有序介孔碳产物具有高比表面积（495 - 777 m²/g）、大孔容（0.32 - 0.47 cm³/g）、纳米级均匀孔径（2.5 - 4.3 nm）以及微米级中空银耳状形态，这可能有利于传质。
