▎ 摘  要

NOVELTY - Preparing graphene complex film comprises (i) preparing the graphene oxide into a uniform aqueous solution of graphene oxide, (ii) assembling the aqueous graphene oxide solution obtained in the step (i) into a self-supporting graphene oxide film to obtain a graphene oxide film by vacuum filtration, (iii) immersing the GO film obtained in the step (ii) in a tetrahydrofuran solution of 10,12-pentacosadien-1-ol (PCO) to obtain the PCO and esterifying the GO nanosheet to obtain a complex film, (iv) irradiating the complex film obtained in the step (iii) with ultraviolet light to obtain a GO-PCO film under the protection of an inert gas, (v) immersing the GO-PCO film obtained in the step (iv) in hydriodic acid (HI), and drying to obtain a covalently crosslinked G-PCO complex film and (vi) immersing the G-PCO film obtained in the step (v) in N-hydroxy-succinimide ester (PSE) and 1-aminoindole (AP) N, N-dimethyl group, washing and drying. USE - The method is useful for preparing graphene complex film. ADVANTAGE - The film has orderly crosslinked pi bond and a covalent bond and super high-conductivity.
