▎ 摘　　要

NOVELTY - The method involves obtaining the surface-attached nitrogen-doped graphene electrode by using the nitrogen-doped graphene. The electrode sheet with nitrogen-doped graphene attached on the surface is placed in an organic electrolyte solution containing Schiff base transition metal polymer monomer and polymerized in situ by an electrochemical method to obtain the composite ultracapacitor electrode material. USE - Method for preparing nitrogen-doped graphene and Schiff base transition metal polymer composite super-capacitor electrode material. ADVANTAGE - The improved method for preparing nitrogen-doped graphene and Schiff base transition metal polymer composite super-capacitor electrode material is provided. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram illustrating the method for preparing nitrogen-doped graphene and Schiff base transition metal polymer composite super-capacitor electrode material.
