The invention discloses a preparation method of monodispersed conductive polymer microspheres with core-shell structure, which relates to a conductive polymer microsphere and provides a preparation method of monodispersed conductive polymer microspheres with core-shell structure. The stabilizing agent and lower alcohol mediator are added to a reactor, stirred and warmed up to dissolve the polyvinyl pyrrolidone; the vinyl monomers dissolved with initiators are added to obtain the polymer dispersion liquid which is then centrifugal separated; the stabilizing agent and lower alcohol adsorbed on the polymer microsphere surfaces are washed out; the polymer microspheres are positioned inside the reactor after being dried, then water is added enabling the polymer microspheres occupying 10% to 30% of the whole reacting system; oxidant is added after ultrasonic decentralization; inorganic acid is added after the oxidant is dissolved; conductive polymer monomers are injected after ice-water bath; and then ice-water bat
