Analysis and Research on characteristics and corrosion resistance of graphene attached to copper surface

The adhesion of graphene on copper surface was studied, and its chemical characteristics corrosion resistance were analyzed. results polarization curve analysis show that the film is best when growth time 7 min. electrochemical impedance spectroscopy shows substrate improved by 17 times. graphite strips prepared at min have uniformity continuity. residue 4 thin but discontinuous. 10 thickest thickness most grain boundary defects. optimal process parameters determined as follows: AR / CH H 2 flow rate ratio 600 40 30 SCCM, temperature 1000 ° C, reaction
