NOVELTY - Synthesis of polyaniline encapsulated graphene particles involves adding graphite oxide to dilute hydrochloric acid solution, adding aniline with ethanol, stirring, adding solution to chloroform, stirring to form emulsion, dissolving ammonium persulfate in hydrochloric acid solution, adding dissolved solution d to emulsion, washing precipitate successively with water and ethanol, placing in vacuum drying oven to obtain graphene oxide/polyaniline composite, refluxing resulting composite and sodium borohydride, filtering, and drying under vacuum. USE - Synthesis of polyaniline coated graphene particles (claimed). ADVANTAGE - The method enables synthesis of polyaniline coated graphene particles with excellent stability and improved electrochemical performance. DETAILED DESCRIPTION - Synthesis of polyaniline encapsulated graphene particles involves adding 14-26 mg graphite oxide to 5-15 ml 0.5 mol/L dilute hydrochloric acid solution, adding aniline with 1-6 ml ethanol such that ratio of aniline and graphene oxide is 2:1, stirring solution for 30 minutes, adding obtained solution to 0.1-0.4 ml chloroform, stirring to form emulsion, dissolving 0.2-0.3 g ammonium persulfate in 5 ml 0.5 mol/L hydrochloric acid solution, adding dissolved solution to emulsion in ice bath, reacting for 18 hours, washing precipitate successively with water and ethanol, placing obtained solution in vacuum drying oven at 60 degrees C to obtain graphene oxide/polyaniline composite, refluxing resulting composite and 280-520 mg sodium borohydride at 100 degrees C for 6-20 hours, suction filtering reaction product, and drying under vacuum overnight.
