Hybrid materials based on organic conjugated polymers and inorganic nanostructures have been at the leading edge of research and development. Electrodeposition is a particularly powerful tool for the in situ polymerization on a nanostructured electrode. In this paper we present examples of hybrid materials based on TiO2 nanotubes and nanoporous WO3, in combination with conjugated polymers as PEDOT, polyaniline and polypyrrole. During optimization of the electrochemical synthesis, particular care was devoted to optimize the structure of the hybrid assembly (e.g., homogenous distribution of the polymer) and the electroactivity of the deposited polymer simultaneously. The limitations of such procedures will be emphasized and generalized solutions will be given to overcome the difficulties arising from the limited electroactivity of the inorganic working electrodes. Finally, it is believed that bringing the inorganic nanostructures and the organic polymer into intimate contact on both physical and electronic levels, will facilitate practical applications of these materials.
