USE - Graphene oxide composite electronic heater (claimed). ADVANTAGE - The graphene oxide composite electronic heater is prepared by simple and economical process. DETAILED DESCRIPTION - A graphene oxide composite electronic heater comprises graphene oxide, nano graphite powder, bamboo carbon fiber, epoxy resin, dicyandiamide, and dimethyl formamide solvent. The graphene oxide composite electronic heater is prepared by (1) placing 10 pts. wt. graphene oxide into 90 pts. wt. purified water having purity of more than 95%, ultrasonically dispersing to prepare oxidized graphene suspension, (2) uniformly mixing 55 pts. wt. nano graphite powder, 15 pts. wt. bamboo charcoal fiber, 18 pts. wt. epoxy resin, 2 pts. wt. dicyandiamide, and 90 pts. wt. dimethyl formamide solvent to prepare a composite, (3) mixing oxidized graphene suspension with composite to prepare oxidized graphene composite conductive adhesive, (4) uniformly coating the oxidized graphene composite conductive adhesive on a surface of a cured glass cloth cured sheet by a screen printing method, drying the surface using hot air blower, uniformly coating the oxidized graphene composite conductive adhesive on other surface of cured glass cloth cured sheet using the same screen printing method, and drying the other surface using hot air blower to produce heating layer, (5) covering copper foil wire fabric electrode on both sides of the heating layer surface with high temperature resistant flame-retardant epoxy resin as an insulator protective layer, pressing at 160 degrees C and 6 MPa for 2 hours to prepare oxidized graphene composite electronic radiator, and (6) cutting and welding the oxidized graphene composite electronic radiator.
