- Аннотация: The development of novel materials with improved functional characteristics for supercapacitorelectrodes is of current concern and calls for elaboration of innovative approaches. We report on aneco-friendly enzymatic synthesis of a composite based on poly(3,4-ethylenedioxythiophene) (PEDOT)and multi-walled carbon nanotubes (MWCNTs). The redox active compound, sodium 1,2-naphthoquinone-4-sulfonate (NQS), was used as a dopant for the backbone of the polymer. Oxidativepolymerization of 3,4-ethylenedioxythiophene (EDOT) was catalyzed by a high redox potential laccasefrom the fungus Trametes hirsuta. Atmospheric oxygen served as an oxidant. A uniform thin layer ofNQS-doped PEDOT formed on the surface of MWCNTs as a result of the enzymatic polymerization.The PEDOT–NQS/MWCNT composite showed a high specific capacitance of ca. 575 F g1 ata potential scan rate of 5 mV s1 and an excellent cycling stability within a potential window between0.5 and 1.0 V, which makes it a promising electrode material for high-performance supercapacitors.
