Abstract. 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, …
