Electrodeposition and characterisation of polypyrroles containing sulfonated carbon nanotubes

J Nanosci Nanotechnol. 2007 Oct;7(10):3487-94. doi: 10.1166/jnn.2007.825.

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.
