NOVELTY - Doping graphene involves preparing electrolyte solution containing deionized water and conductive polymer precursor. The conductive polymer precursor comprises conductive high molecular thiophene precursor, thiophene derivative, pyrrole or aniline. The graphite and copper foil substrate are immersed in electrolyte solution and then the immersed material is connected with working electrode. The power is supplied into the electrode for attaching copper foil substrate on graphene surface to obtain conducting polymer film-graphene-copper composite structure. The obtained material is immersed. USE - Method for doping graphene (claimed). ADVANTAGE - The method enables to perform doping of graphene in simple manner, with high controllability and uniform thickness, and has improved mechanical strength. DETAILED DESCRIPTION - Doping graphene involves preparing electrolyte solution containing deionized water and conductive polymer precursor. The conductive polymer precursor comprises conductive high molecular thiophene precursor, thiophene derivative, pyrrole or aniline. The graphite and copper foil substrate are immersed in electrolyte solution and then the immersed material is connected with working electrode. The power is supplied into the electrode for attaching copper foil substrate on graphene surface to obtain conducting polymer film-graphene-copper composite structure. The obtained material is immersed in cleaning agent liquid for 1-3 minutes and then dried. The conducting polymer-graphene growth substrate and copper foil are transferred to the target substrate surface to obtain the desired product, where the target substrate is a polyethylene terephthalate or polyethylene naphthalate.
