▎ 摘　　要

Multilayer films stacked alternately by poly(3,4-ethylenedioxythiophene) and reduced graphene oxide were synthesized electrochemically from a single aqueous solution containing 3,4-ethylenedioxythiophene (EDOT) and graphene oxide (GO) by repeatedly oxidizing EDOT and reducing GO on a conductive substrate. Using the proposed technique, the thickness of the different layers could be easily tuned by varying the electrolysis time, and the number of layers could be increased simply by repeating the sequence of potential steps.
