Organic conducting fibres based on either inherently conducting polymers (polyaniline) or
carbon nanotubes (CNTs) have previously been produced. In this work the integration of
CNTs into polyaniline fibres has been achieved using wet spinning techniques. It is shown
that addition of small amounts of CNTs significantly improves the mechanical, electronic and
electrochemical properties of the polyaniline fibre. These improved properties result in
increased electromechanical actuation when used as artificial muscle fibres.
