NOVELTY - The preparation of graphene oxide composite film involves adding graphene oxide to deionized water, ultrasonically dispersing for 1-2 hours, adding 1-indolebutyric acid, ultrasonically treating for 30-60 minutes to obtain dispersion (A), dissolving chitosan in acetic acid solution having concentration of 0.5-2 wt.%, adding polyvinylpyrrolidone, hydroxyethyl cellulose, magnetically dispersing uniformly to obtain dispersion (B), mixing dispersion (A) and dispersion (B) uniformly, adding polyaniline, stabilizer and plasticizer, and ultrasonically vibrating for 30-60 minutes to uniformly disperse the mixed slurry, vacuum filtering mixed slurry into a film, and drying in a vacuum drying oven at 60 degrees C. USE - Preparation of graphene oxide composite film. ADVANTAGE - The method enables preparation of high stability graphene oxide composite film with high mechanical and high electrical properties and high graphene dispersibility, promotes the uniform dispersion of graphene in the polymer matrix, improves dispersibility in aqueous media and avoids agglomeration of graphene.
