Abstract

This paper describes a simple approach to prepare manganese dioxide/poly(3,4-ethylenedioxythiophene) (MnO 2/PEDOT) core/sheath nanowires with a controlled sheath thickness in the range of 2-10 nm. The PEDOT coating on a MnO 2 nanowire was performed by immersing the nanowires in an acidic solution containing 3,4-ethylenedioxythiophene (EDOT) monomers. Analysis of opencircuit potential of the MnO 2 nanowire electrode in the solution indicates that a galvanic displacement reaction between MnO 2 and EDOT is responsible for the synthesis of the MnO 2/PEDOT core/sheath nanowire.
