Problems solved by technology

At present, graphene research at home and abroad focuses more on its electrical conductivity and optical properties. In textiles, some researchers try to use graphene instead of conductive carbon black to produce antistatic fibers with lower resistivity; and use graphene or carbon black mixtures as Infrared-emitting materials are used, but the heat transfer properties of graphene have not been seen in textiles, especially in protective clothing.
