▎ 摘  要

NOVELTY - Preparing high performance graphene comprises (1) adding modified oxide graphene polyacrylic acid and polyamide to dimethylformamide (DMF), ultrasonically processing for 30 minutes, stirring for 2 hours at room temperature to obtain the spinning solution, (2) using spinning solution for electrostatic spinning, after spinning, vacuum drying to obtain graphene fiber. USE - The method is useful for preparation of high performance graphene. ADVANTAGE - The method improves the interface compatibility with the polymer, promotes the uniform dispersion of the oxidized graphene in the polymer, can form more effective conductive network, convenient for electronic conduction, improves the conductivity of the graphene fiber, polyamide can form interpenetrating network structure with polyacrylic acid, and between the two has strong hydrogen bond effect and can improve the mechanical property of the fiber.
