NOVELTY - Chemical vapor deposition technique of high molecular nanocomposite preparation involves preparing loaded nickel copper foil comprising depositing nickel and heat treating at 865-875 degrees C for 5-8 minutes, naturally cooling to normal temperature, using argon gas and hydrogen mixed gas as protective gas, depositing under certain temperature condition, cooling at rate of 10 K/second, removing deposited graphene when substrate is cooled to 200 degrees C, removing removed graphene material from organics and heavy metals, and preparing graphene-nano inorganic composites. USE - The method is used for chemical vapor depositing high molecular nanocomposite preparation.
