DETAILED DESCRIPTION - Preparing graphene coating on stainless steel surface involves preparing polishing 600 mesh, 1000 mesh, and 1500 mesh metallographic sandpaper, polishing stainless steel following by acetone, ethanol, and deionized water, and ultrasonic cleaning for 20 minutes for pre-treating stainless steel. The oxidized graphene dissolved is dissolved in deionized water to obtain concentration of 1-10 milligram/milliliter graphene solution. The pretreated stainless steel side of drop surface, aqueous solution of graphene oxide at concentration of 1-10 milligram/milliliter is dropped on drip surface of pretreated stainless steel at rate of 5-20 micro liter/square centimeter, adjusted rotational speed of spin coater to 1000-3000 revolutions per minute, spin-coated for 5-30 seconds. The spin-coated stainless steel is placed in oven at a temperature of 100 degrees C for 10-30 minutes. The surface is covered with thin film of stainless steel in accordance for 1-5 times. The stainless steel coated with graphene layer is placed in plasma chemical vapor deposition vacuum apparatus, evacuated to pressure of 5 Pascal, introduced with hydrogen gas, adjusted to hydrogen gas flow rate of 40 standard cubic centimeter per minute, and adjusted evacuation speed. The plasma enhanced chemical vapor deposition vacuum apparatus pressure is 200-500 Pascal, and increased temperature to 600 degrees C, and flow rate is 200-600 Watt for 30 minutes. The vertical growth of stainless steel surface in situ graphene includes closed RF, and pressure is 200-500 Pascal under temperature of 600-800 degrees C into methane gas and argon, adjusted methane gas gas flow rate of 1-100standard cubic centimeter per minute, and adjusted argon gas flow rate of 1-100 standard cubic centimeter per minute, regulation of hydrogen gas flow rate of 1-100 standard cubic centimeter per minute. The vacuum speed of plasma enhanced chemical vapor deposition vacuum device pressure controlled at pressure of 100-1000 Pascal, and RF power of 20-800 Watt, at pressure of 100-1000 Pascal, methane gas flow rate is 1-100 standard cubic centimeter per minute, argon gas flow rate of 1-100 standard cubic centimeter per minute, and hydrogen gas flow rate to 1-100 standard cubic centimeter per minute, at temperature of 600-800 degrees C under conditions of deposition for 1-120 minutes, closing power supply, stopped inletting methane gas, under protection of argon gas and hydrogen gas atmosphere, and cooled to room temperature to obtain final product.
