▎ 摘　　要

NOVELTY - A two-dimensional, graphene-based porous polymer, comprises a graphene layer which is sandwiched between the porous polymer, in which the porous polymer is microporous. The graphene layer is sandwiched between the porous polymer by covalent bond. USE - Two-dimensional, graphene-based porous polymer e.g. Schiff base-type two-dimensional, graphene-based porous polymer is used in light harvesting, sensing, gas-separation and storage, catalysis, energy storage and conversion, and for forming porous carbon used in manufacture of electrochemical double layer capacitor and supercapacitor (all claimed). ADVANTAGE - The two-dimensional, graphene-based porous polymer has excellent stability, and is manufactured easily and economically with high productivity, and provides porous carbon which has high heteroatom content and large surface area, and excellent supercapacitor characteristics, without using graphene template. The porous carbon is readily fabricated in a template-free manner by thermal pyrolysis. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) porous carbon; (2) manufacture of two-dimensional, graphene-based porous polymer; and (3) manufacture of Schiff base-type two-dimensional, graphene-based porous polymer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view explaining the preparation of graphene-based two-dimensional conjugated microporous polymer and graphene-based two-dimensional mesoporous carbon.
