NOVELTY - Preparing dry spinning of high strength conductive graphene fiber, involves oxidized grapheme dispersing in low boiling point solvent, making mass concentration of sol-gel spinning liquid is 1-20%, the spinning solution from spinning nozzle capillary tube of continuous constant speed extruded by the spinning device, the hot air drying and solidifying to obtain the graphene oxide fiber, process chemical reduction, to obtain the graphene. USE - As dry spinning preparation method of high strength conductive graphene fiber (claimed). ADVANTAGE - The spinning method is simple, not by coagulating liquid, the method is environment-friendly, the obtained graphene fiber has good conductivity, excellent mechanical property, good flexibility and can be pure woven graphite fiber cloth, but also can be mixed all kinds of woven fabric with air-purifying function and other fiber. DETAILED DESCRIPTION - Preparing dry spinning of high strength conductive graphene fiber, involves stirring and reacting raw material components comprising (part by weight): raw material graphite, copper sulfate (100), potassium peroxydisulfate (0.5) and phosphorus pentoxide (0.5) at 25-10 degrees C for 10 hours, after cooling to room temperature, diluting with de-ionized water, filtering by filter film, using de-ionized water to wash the solution until it is neutral, drying for 50 hours to obtain the intercalated graphite, intercalated graphite, sulfuric acid (100) and potassium permanganate (0.5-10), after stirring and reacting for 10 hours at 50 degrees C, adding deionized water (10-2000) and hydrogen peroxide solution to stir for 1 hours to filter membrane, repeatedly washing by deionized water solution until it is neutral, drying to obtain the primary oxidized graphite, to obtain the primary oxidized graphite, sulfuric acid (100) and potassium permanganate (0.5-10), at 50 degrees C to agitate and react for 10 hours, adding deionized water (10-2000) and hydrogen peroxide solution to stir for 1 hours to filter membrane, repeatedly washing by deionized water solution until it is neutral, drying to obtain the grapheme oxide, to obtain the graphene oxide product solvent (5-100), ultrasonic processing for 10-50 KHz for 10 hours, to obtain grapheme oxide sol-gel spinning solution, taking the workpiece to obtain graphene oxide sol-gel spinning liquid, solidifying filamentation in hot air to obtain the graphene oxide fiber, to obtain the graphene oxide fiber reducing agent in 0.100 hour, washing and drying, obtaining the high intensity macroscopic graphene conductive fiber.
