▎ 摘　　要

NOVELTY - Forming purified graphene oxide (GO) material, involves forming 110 a GO suspension 112 comprising GO, dewatering 120 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 132 comprising a solvent, and filtering 130 the GO solution through a second filter to form the purified GO material having a particle size of 2-50 mum. USE - Method for forming purified graphene oxide (GO) material that is utilized in inkjet printing, screen printing, printed circuit boards, radio frequency 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 enables facile, high-throughput production of GO materials with high purities. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of dead-end filtering method for forming a graphene oxide (GO) material.
