| titleOfInvention | Reduced graphene oxide/polyacrylonitrile composite fiber and preparation method thereof |
| abstract | The invention relates to a reduced graphene oxide/polyacrylonitrile composite fiber and a preparation method thereof, wherein the method comprises the following steps: and assembling the graphene oxide on the surface of the polyacrylonitrile fiber containing the amino group through electrostatic attraction and chemical bonding, and then carrying out reduction treatment to obtain the reduced graphene oxide/polyacrylonitrile composite fiber. The average volume resistivity of the reduced graphene oxide/polyacrylonitrile composite fiber prepared by the method is less than or equal to 30 omega cm, the reduced graphene oxide/polyacrylonitrile composite fiber is reduced by 12 orders of magnitude relative to the precursor, meanwhile, the reduction rate of the breaking strength relative to the precursor is less than or equal to 5%, the increase rate of the breaking elongation relative to the precursor is more than or equal to 58%, and after the composite fiber is washed by deionized water for 10-20 times, the average volume resistivity of the fiber is less than or equal to 33 omega cm. The method has the advantages of diverse selection of the reducing reagent, good reducing effect, low production cost and the like, and the prepared fiber has good conductivity and durability, and the excellent mechanical property of the fiber is retained. |
