Electrodeposition and characterisation of polypyrroles containing sulfonated carbon nanotubes

Journal Article


Abstract


  • Using facile diazonium chemistry, sulfonate groups have been covalently attached to single wall carbon

    nanotubes. The resulting sulfonated tubes form a stable aqueous dispersion in the presence of

    pyrrole monomer. Subsequent electropolymerisation results in a conductive, electroactive polypyrrole

    doped with sulfonated tubes being formed at unusually low potentials. The potential of this

    material as a host matrix for biomolecules has been demonstrated by entrapping horse-radish

    peroxidase directly in the polypyrrole during composite formation.
