Abstract

The invention relates to the material field and provides a polymer composite with plasticity. The polymer composite with plasticity and with plasticine characteristic is synthesized through evaporation-induced self-assembly of a solvent by mixing a mixed surfactant and an organic polymer. The polymer composite is further roasted and the surfactant is removed to obtain an ordered mesoporous polymer of multi-level structure, and the ordered mesoporous polymer is carbonized at high temperature to obtain an ordered mesoporous carbon material of multi-level structure. Being plastic, the shape of the polymer composite is not damaged before and after roasting, the mesoporous polymers and carbon materials of different shapes can be obtained after carrying out post-forming on the polymer composite, and the macro shapes of the mesoporous polymers and carbon materials are not damaged. The obtained carbon materials have the characteristics of open multi-level pore channel structures, high specific surface, large pore volume, uniform mesopore diameter and the like.

Description

Technical field [0001] The present invention relates to the field of materials, in particular to a polymer compound with "plasticine" properties and plasticity, and an ordered mesoporous polymer with a hierarchical structure and a hierarchical structure prepared by using this compound Mesoporous carbon material. Background technique [0002] Mesoporous polymers and carbon materials are widely used in many fields such as adsorption, separation, catalysis, electrode materials, etc. due to their low cost, large surface area and controllable pore structure. The synthesis of ordered mesoporous carbon and mesoporous polymer can generally be obtained by organic organic self-assembly or hard template method. The mesoporous pores of mesoporous carbon obtained by the hard template method come from the gaps between the carbon rods. Therefore, the pore size distribution is relatively wider than that of the mesoporous silica template. In addition, the use of mold mesoporous silica makes th...
