▎ 摘　　要

NOVELTY - Manufacture of ink-injectable printing flexible electrode involves dispersing the conductive polymer coaxial nanotube composite material and graphene oxide in anhydrous ethanol to obtain electrode ink, evaporating solvent anhydrous ethanol until the solid content reaches 10 mg/mL or more, preferably 10-20 mg/mL, using carbon cloth as the substrate, subjecting to printing using electrode ink by gel device, reducing under hydrazine hydrate stream atmosphere. The mass ratio of conductive polymer coaxial nanotube composite material and graphene oxide is (1-10): 1, preferably (5-8):1. The conductive polymer coaxial nanotube composite material is a polypyrrole/polyaniline coaxial nanotube composite material. USE - Manufacture of flexible electrode used as supercapacitor electrode material (claimed). ADVANTAGE - The manufactured flexible electrode is size adjustable and controllable density, has excellent flexibility and bending property.
