▎ 摘　　要

NOVELTY - Graphene oxide-based imidazole porous polymer (I) is new, prepared by crosslinking o-diamino compound with graphene oxide or its derivative, where the graphene oxide is provided with oxygen-containing functional groups. The oxygen-containing functional group is carboxy group, the graphene oxide derivative is a product obtained by reacting graphene oxide with chloroacetic acid, N-(2-hydroxyethyl)iminodiacetic acid or N-(2-hydroxyethyl)ethylenediamine-N,N,N'-triacetic acid, and molecular structure of the o-diamino compound contains two or more o-diamino groups. USE - (I) is useful in carbon dioxide adsorption and supercapacitor (claimed). ADVANTAGE - (I) has high specific surface area, good carbon dioxide adsorption capacity, excellent thermal stability and high specific capacitance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of (I).
