Abstract
Poly(3,4-ethylenedioxythiophene)-polystyrenesulfonate and manganese oxide (PEDOT:PSS/MnO2) hybrids were prepared via a facile solvothermal method coupled with an oxidative polymerization route. The effects of the reaction temperature and the KMnO4-to-organic monomer (3,4-ethylenedioxythiophene, EDOT) ratio on the morphology, structure, and electrochemical properties of the materials were investigated. The optimized composites comprised homogeneous nanorod-like structures and exhibited overwhelmingly high conductivity (36Scm(-1)) and superior supercapacitancemore specifically, they exhibited high-rate capability. The electrochemical properties of the nanocomposites were investigated using cyclic voltammetry and galvanostatic charge-discharge cycling. The prepared hybrids showed a high capacitance of 365.5Fg(-1) at a current density of 1Ag(-1), a good rate performance of 325.4Fg(-1) at 20Ag(-1) (capacitance retention of 89%), and excellent cycling stability with approximately 80% capacitance retention after 2000cycles at a current density of 5Ag(-1) in a 6M KOH aqueous electrolyte.
