▎ 摘  要

NOVELTY - An amine compound modified graphene film, is new, and is obtained by sequentially reducing graphene oxide film by amine compound solution containing amino groups. USE - Amine compound modified graphene film is used in preparation of graphene functional materials (claimed). ADVANTAGE - The amine compound modified graphene film has low mechanical strength, improves the mechanical performance of the axial stress transfer and assembly body between the connecting graphene sheet, large area graphene sheet conjugate can form an expanded electronic cloud, so as to realize high electron mobility on the graphene sheet, tensile strength of the film is 1.70 ± 0.05 GPa, Young modulus is 131 ± 12 GPa, and the conductivity is 1.0×105S m-1. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of amine compound modified graphene film, which involves preparing graphene oxide film from the graphene oxide aqueous solution; then soaking graphene oxide film in the amine compound aqueous solution for 1-300 minutes, soaking in the reducing agent aqueous solution for 1-50 hours to obtain the amine compound modified graphene film.
