▎ 摘　　要

NOVELTY - Manufacture of polyaniline-reduced graphene oxide composite involves dispersing graphene oxide in acid aqueous solution containing emulsifying agent, obtaining graphene oxide dispersion, dissolving aniline oligomer in organic solvent, obtaining oligomer solution, mixing resultant with graphene oxide dispersion, adding oxidizing agent to resultant suspension and oxidizing. The usage amount of oligomer is more than the content of graphene. USE - Manufacture of polyaniline-reduced graphene oxide composite used as ink for electromagnetic application and element for capacitor, super capacitor (all claimed), sensor and membrane. ADVANTAGE - The method enables manufacture of polyaniline-reduced graphene oxide composite having excellent electroconductivity, stability and workability, by simple process, within short period of time, without using toxic reagent.
