NOVELTY - Dehumidifying porous graphene at high voltage comprises selecting two graphene plates that are parallel to each other, locating the water molecules between the two graphene plates to remain the defects on the graphene plates, where the defect aperture is greater than or equal to 7.7 angstroms, applying electric field perpendicular to the graphene plates outside the graphene plates and leaving the water molecules from the defect, where the electric field strength is greater than or equal to 1V/nm. USE - The method is useful for dehumidifying porous graphene at high voltage. ADVANTAGE - The method: does not require additional chemical reagents; has relatively weak electric field, so the drying cost is economical and rapid drying speed by the electric field and good drying stability; and reduces the energy consumption.
