The adhesion of graphene on copper surface was studied, and its chemical characteristics and corrosion resistance were analyzed. The results of polarization curve analysis show that the corrosion resistance of graphene film is the best when the growth time is 7 min. electrochemical impedance spectroscopy shows that the corrosion resistance of copper substrate is improved by 17 times. The graphite strips prepared at 7 min have the best uniformity and continuity. The graphite residue at 4 min is thin but discontinuous. The graphite strips at 10 min have the thickest thickness but the most grain boundary defects. The optimal process parameters were determined as follows: AR / CH4 / H2 flow rate ratio 600 / 40 / 30 SCCM, temperature 1000 ° C, reaction time 7 min.
