NOVELTY - Preparation of high-conductivity ferric chloride-doped graphene nano-powder material, involves mixing anhydrous iron chloride powder, flake graphite powder and phosphorus pentoxide powder in dry environment, adding into stainless steel reactor, evacuating reactor, then adding mixture of chlorine gas and protective gas, cooling, cleaning the obtained material and drying to obtain iron chloride intercalated graphite with special intercalation structure, adding intercalated graphite to aqueous solution containing hydrogen peroxide and complexing agent to carry out swelling and peeling. USE - Preparation of high-conductivity ferric chloride-doped graphene nano-powder material for use in preparation of printed electronic device. ADVANTAGE - The conductivity of the graphene powder material can reach 5000 S/cm or more. The precious metals can be replaced with highly conductive material in the preparation of printed electronic devices, so that the production cost of printed electronic devices can be reduced and performance of the printed electronic devices can be improved. DETAILED DESCRIPTION - Preparation of high-conductivity ferric chloride-doped graphene nano-powder material, involves mixing evenly anhydrous iron chloride powder, flake graphite powder and phosphorus pentoxide powder in a dry environment, adding into stainless steel reactor, evacuating the reactor and then adding mixture of chlorine gas and protective gas, and cooling at 350-400 degrees C for 5-12 hours, cleaning the obtained material and drying to obtain iron chloride intercalated graphite with special intercalation structure, adding the intercalated graphite to an aqueous solution containing hydrogen peroxide and complexing agent to carry out swelling and peeling, then collecting the stripped material which is ferric chloride-doped graphene nano-powder material.
