▎ 摘　　要

NOVELTY - Producing graphene aerogel involves preparing graphene oxide dispersion using graphene oxide stripping method. The graphene dispersion is uniformly mixed with amine curing agent to obtain graphene oxide mixed solution. The amine curing agent is selected from diaminodiphenylmethane, diaminodiphenylsulfone, diethylenetriamine, triethylenetetramine, bis(2-aminodiphenylmethane)diamine, ethylenediaminopropylamine and m-phenylenediamine. The graphene oxide mixed solution is heated and selaed at 90-120 degrees C to reduce the graphene oxide by the amine curing agent to obtain graphene hydrogel. USE - Method for producing graphene aerogel used for improving electrical and mechanical properties of epoxy resin (claimed). ADVANTAGE - The method enables to produce graphene aerogel that has high conductivity, excellent mechanical property and high porosity. DETAILED DESCRIPTION - Producing graphene aerogel involves preparing graphene oxide dispersion using graphene oxide stripping method. The graphene dispersion is uniformly mixed with amine curing agent to obtain graphene oxide mixed solution. The amine curing agent is selected from diaminodiphenylmethane, diaminodiphenylsulfone, diethylenetriamine, triethylenetetramine, bis(2-aminodiphenylmethane)diamine, ethylenediaminopropylamine and m-phenylenediamine. The graphene oxide mixed solution is heated and selaed at 90-120 degrees C to reduce the graphene oxide by the amine curing agent to obtain graphene hydrogel. The obtained graphene hydrogel is sequentially washed with acetone and water and then freeze-dried to obtain graphene aerogel.
