▎ 摘　　要

NOVELTY - Composite gel of modified carbon fiber based on asymmetric oxidation graphene comprises a water-soluble polymer hydrogel loaded with asymmetric graphene modified carbon fiber. The asymmetric graphene modified carbon fiber is attached with asymmetric graphene oxide of carbon fiber. The carbon-oxygen ratio of the asymmetric graphene oxide is 1-12. The ID/IG of the hydrophilic end is not less than 1 and the ID/IG of the hydrophobic end is less than 1. USE - The material is useful in the mechanical equipment, preferably sensors, capacitors, electrodes, electromagnetic shielding and/or electronic skin (claimed). ADVANTAGE - The material: is simple, green, easy to scale production and environment-friendly; has high efficiency and excellent interface adhesion effect and improves the interface adhesive property. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a composite gel material comprising polyvinyl alcohol solution, asymmetric oxidation dispersion graphene and carbon fiber. The concentration of the aqueous-soluble polymer solution is 2-20%. The concentration of the asymmetric oxidation dispersion graphene is 0.1-3 mg/ml. The carbon-oxygen ratio of the asymmetric graphene oxide is 1-12 and the ID/IG of the hydrophilic end is ≮ 1 and the ID/IG of the hydrophobic is less than 1; and preparing composite gel comprising soaking the asymmetric graphene modified carbon fiber in the aqueous-soluble polymer solution, drying and molding to obtain the composite material gel.
