Abstract

A new approach is proposed, namely the use of Interpenetrating Polymer Networks (IPNs) in order to solve the interface and adhesion problems in the design of classical conducting polymer based actuators. Semi IPN type materials are synthesized between poly(3,4-ethylenedioxythiophene) and a poly(ethyleneoxide) based network as the ionic conducting partner. The synthetic pathway which will be presented ensures a gradual dispersion of the electronic conducting polymer through the thickness of the material i.e. the content decreases from the outside towards the center of the film. The system is thus similar to a layered one with the advantage that the intimate combination of the two polymers needs no adhesive interface. The influence of the morphology and chemical composition of the matrix on the electronic conductivity of the material have been studied. The surface conductivity can reach 15 S/cm. Finally, this material is capable of a 45 degree(s) angular deflexion under a 0.5 V potential difference.
