NOVELTY - A graphene carbon-coated copper nano-wire network preparing method involves synthesizing nano-copper wire through ultrasonic dispersion and vacuum filtration, depositing copper wire on cellulose nitrate film to form a thin film, treating the oxide surface with dihydrogen and methane, and subjecting to optical microscope and SEM test to observe the growth of graphene thin copper foil. The silicon nano-wire with copper sheet is placed into a CVD reaction chamber for heating to prepare a sample followed by subjecting to cooling and annealing process to obtain a finished product. USE - Method for preparing a graphene carbon-coated copper nano-wire network. DETAILED DESCRIPTION - A graphene carbon-coated copper nano-wire network preparing method involves synthesizing nano-copper wire through ultrasonic dispersion and vacuum filtration, depositing copper wire on cellulose nitrate film to form a thin film for covering the nano-wire upper substrate, folding the copper foil into boat-shaped by heating at 700 plus minus 30 degrees C, subjecting the copper foil to a CVD reaction chamber at heating temperature area with gas pressure and quartz reaction cavity for heating, treating the oxide surface with dihydrogen and methane and subjecting to optical microscope and SEM test to observe the growth of graphene thin copper foil. The silicon nano-wire with copper sheet is placed in a quartz boat by sealing with copper foil capsule and pushed into the CVD reaction chamber for heating under vacuum at 200 degrees C to prepare a sample. The sample is placed in a heating zone at 400-900 degrees C to obtain a reaction. The sample is pulled out when the temperature is reached to 700 degrees C followed by treating the sample with dihydrogen and methane and subjecting graphene coated carbon film to cooling and annealing process to obtain a graphene carbon-coated copper nano-wire network.
