NOVELTY - Forming purified graphene oxide (GO) material comprises: forming a GO suspension comprising GO; dewatering the GO suspension with a first filter to form a dewatered GO suspension; forming a GO solution comprising the dewatered GO suspension and a solvent solution; and filtering the GO solution through a second filter. USE - The method is useful for forming purified graphene oxide (GO) material comprising GO powder, an anhydrous GO powder, an intercalated GO powder, an exfoliated GO powder, a single layer GO material, a water dispersible GO material, a polar solvent dispersible GO material, an aqueous GO material, a GO ink, a GO paste, a GO solution, a GO fluid, a GO liquid, a GO paint, a GO dye, a GO coating and/or GO compound (claimed) and useful in printing, screen printing, printed circuit boards, radio identification chips, smart fabrics, conductive coatings, gravure printing, flexographic printing, batteries, supercapacitors, electrodes, electromagnetic interference shielding, printed transistors, memory, sensors, large area heaters, electronics, membranes, anti-static coatings, and energy storage systems. ADVANTAGE - The method provides the GO material that: has a surface area of 800-2400 m2/g and conductivity of 0.1-5 S/m and oxidation percentage of 15-60%; avoid the shortcomings of current forming methods to facilitate facile, high-throughput production of GO materials.
