NOVELTY - A copper film is contacted with a gas, the temperature of the copper film is raised to 1000 degrees C over 40 minutes, and the copper film is heated at 1000 degrees C for 1 hour. The resultant copper film is contacted with a carbon-containing gas for 5 minutes, and cooled to room temperature to produce a graphene layer on the copper film. USE - Manufacture of graphene. Uses include but are not limited to electronic devices, photonics, photovoltaics, energy generation and storage, nanotube production, electrodes, production of membranes for sensing pressure and chemicals, components for nanoelectromechanical systems, transistors, thin protective coating against acids and alkali, lithium ion batteries, etc. ADVANTAGE - The method provides graphene within short period of time. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of copper film to catalyze graphene production, which involves washing copper film with a solvent, adding the copper film to a mixture of ethylene glycol and acid in water, adding a cathode plate to the mixture and connecting the cathode plate to a negative electrode, connecting the copper film to a positive electrode, passing current between the cathode plate and the copper film, and removing the copper film and cleaning the copper film with water.
