▎ 摘　　要

NOVELTY - Preparation of polyaniline-graphene nanocomposite involves mixing graphite and a solvent, filtering, drying to obtain exfoliated graphene, mixing exfoliated graphene, aniline and solvent, mixing aniline solution and ammonium peroxide disulfide solution, filtering and drying. USE - Preparation of polyaniline-graphene nanocomposite for optoelectronic device (all claimed). ADVANTAGE - The polyaniline-graphene nanocomposite having excellent electrochemical properties and low resistance is produced without generating agglomeration of particles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for polyaniline-graphene nanocomposite.
