NOVELTY - Preparation of organic aerogel comprises taking phenol, amine, aldehyde, catalyst and solvent as reaction system, adding graphite alkene material comprising active functional groups as crosslinking agent, curing to obtain organic gel, obtaining organic aerogel in normal pressure drying or direct heating and drying, and processing organic gas gel pyrolysis to obtain graphene and crosslinking type carbon aerogel in inert atmosphere. USE - Method for preparing organic aerogel (claimed). ADVANTAGE - The method is simple and fast, and avoids conventional supercritical drying process. DETAILED DESCRIPTION - Preparation of organic aerogel comprises taking phenol, amine, aldehyde, catalyst and solvent as reaction system, adding graphite alkene material comprising active functional groups as crosslinking agent, curing to obtain organic gel, obtaining organic aerogel in normal pressure drying or direct heating and drying, and processing organic gas gel pyrolysis to obtain graphene and crosslinking type carbon aerogel in inert atmosphere, in ratio of phenol, aldehyde, amine of 1:2-4:0-1, each liter of solvent comprising reaction monomer of 50-400, reactive monomer comprising phenol, aldehyde and amine, with liter of solvent comprising graphite alkene material of 5-200 wt.%, and molar ratio of phenol and catalyst of 5-500:1.
