NOVELTY - 1-Aminopyrene and bis(N-hydroxysuccinimide)suberate are added to solution of dimethylformamide and stirred to form dimethylformamide solution containing 1-aminopyrene and bis(N-hydroxysuccinimide)suberate. Oxidized graphene is stirred and ultrasonically processed to form homogeneously oxidized graphene aqueous solution. The graphene-enriched aqueous solution is self-assembled and reduced to form reduced graphene oxide film. The reduced graphene oxide film is immersed in dimethylformamide solution, soaked and pi - pi adsorbed, to obtain biomimetic layered graphene composite material. USE - Preparation of pi - pi conjugated toughness and integrated high-conductivity biomimetic layered graphene composite material used for aerospace field, and flexible electronic device. ADVANTAGE - The method enables preparation of pi - pi conjugated and integrated biomimetic layered graphene composite material with excellent strength, toughness and electroconductivity, and high conductivity. DETAILED DESCRIPTION - 1-Aminopyrene as small molecules and bis(N-hydroxysuccinimide)suberate are added to solution of 11-13 mmol/L dimethylformamide. The mixed solution is stirred for 9-10 hours in dark condition such that the two molecules are completely reacted to form dimethylformamide solution containing 1-aminopyrene and bis(N-hydroxysuccinimide)suberate having amide bonds. Oxidized graphene is stirred and ultrasonically processed to form homogeneously oxidized graphene aqueous solution. The graphene-enriched aqueous solution is self-assembled to film structure by vacuum filtration method and reduced with hydroiodic acid to form reduced graphene oxide film. The reduced graphene oxide film is immersed in dimethylformamide solution containing 1-aminopyrene and bis(N-hydroxysuccinimide)suberate in dark condition, soaked for 23-25 hours and pi - pi adsorbed, to obtain pi - pi conjugated toughness and integrated high-conductivity biomimetic layered graphene composite material. The concentration of 1-aminopyrene and bis(N-hydroxysuccinimide)suberate are controlled, and concentration of dimethylformamide solution containing 1-aminopyrene and bis(N-hydroxysuccinimide)suberate is regulated. The stirring of mixed solution, formation of homogeneously oxidized graphene aqueous solution, self-assembling film structure and reduction with hydroiodic acid are repeated with different concentrations of dimethylformamide solution containing 1-aminopyrene and bis(N-hydroxysuccinimide)suberate.
