▎ 摘　　要

NOVELTY - A ternary nanocomposite material comprises nano cobalt ferrite loaded into graphene sheet layer and coated with polyaniline. The mass ratio of cobalt ferrite and is 1-40%. The concentration of polyaniline is 50-90 wt.%. USE - Ternary nanocomposite material used for catalytic materials and electrode materials. ADVANTAGE - The composite material has excellent electrochemical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of nanocomposite material comprising dispersing nano cobalt ferrite and graphene composite material and ammonium persulfate in acid solution, adding into polyaniline under ice state, reacting to 0-25 degrees C, filtering, and drying.
