NOVELTY - Preparation of graphene-induced polypyrrole nanowire conductive composite material involves mixing three-dimensional layered graphene/flexible substrate with pyrrole and surfactant at the speed of 600 rpm, where the mass ratio of pyrrole with respect to surfactant is 1:0.5-2, gradually adding oxidant and dopant mixed solution under ice-bath condition such that molar ratio of oxidant with respect to dopant is 1:0.2-2, and reacting for 1-5 hours. USE - Preparation of graphene-induced polypyrrole nanowire conductive composite material used for wearable electronic product, electrochemical transistor electrode material, supercapacitor electrode material, microbial fuel cell and sensor. ADVANTAGE - The method efficiently provides graphene-induced polypyrrole nanowire conductive composite material having high specific surface area, and excellent conductivity and reproductivity, by simple method. DETAILED DESCRIPTION - Preparation of graphene-induced polypyrrole nanowire conductive composite material involves immersing a flexible substrate in 0.2-5% three-dimensional layered graphene solution prepared by improved Hammers method, soaked for 1-10 hours, suspending in a reaction kettle, adding 5-30 ml reducing agent, heating in fume hood water bath at 60-100 degrees C, thermally reacting for 1-4 hours, obtaining three-dimensional layered graphene/flexible substrate, mixing obtained substrate with pyrrole and surfactant at the speed of 600 rpm, where the mass ratio of pyrrole with respect to surfactant is 1:0.5-2, gradually adding oxidant and dopant mixed solution under ice-bath condition such that molar ratio of oxidant with respect to dopant is 1:0.2-2, and reacting for 1-5 hours.
