NOVELTY - 0.01-0.05 L/g Carbon nanotube is added to strong acid, refluxed at 120-140 degrees C for 4-8 hours, carbon nanotube is taken, washed with deionized water and filtered. Carbon nanotube is added in a container, deionized water is added, heated at 80-100 degrees C, and added in an ultrasonic crusher for 0.5-2 hours. The mass ratio of carbon nanotube and deionized water is 1:20-100. The carbon nanotube is washed with deionized water, filtered, washed with ethanol, and dried to obtain graphene nano belt. USE - Manufacture of graphene nano belt (claimed). ADVANTAGE - The graphene nano belt is easily and economically manufactured.
