Aniline polymerization on multiwall carbon nanotubes with immobilized laccase

A composite material consisting of electrically conductive polyaniline deposited on the surface of multiwall carbon nanotubes has been synthesized. Enzymatic synthesis was carried out in the presence of Trametes hirsuta laccase immobilized on the nanotube surface. The obtained composite was morphologically uniform, and its electrochemical capacity and stability were much higher than those of a composite synthesized according to the conventional chemical procedure.
