▎ 摘　　要

NOVELTY - Preparing graphene nanofiber cotton comprises preparing a polymer spinning dope, adding graphene stock solution into the polymer spinning dope, and mixing uniformly to form composite spinning dope, introducing composite spinning dope into the nozzle of the spray gun, spraying the composite spinning dope from the nozzle into the drawing cavity by using a spray gun, drawing the composite spinning dope droplet into nanofiber cotton having diameter of 100 nm by using high temperature and high pressure air generated by a high temperature and high pressure air generator. USE - The method is useful for preparing graphene nanofiber cotton. ADVANTAGE - The graphene nanofiber cotton has antibacterial agent and composite antioxidant, which greatly improves use performance of the spinning raw liquid.
