Fabrication and properties of electrode material composed of ordered titania nanotubes and pEDOT:PSS

Abstract

We report on the two-stage preparation method of electrode material composed of titania nanotubes and poly(3,4-ethylenedioxythiopene):poly(2-styrenesulphonate) conductive polymer (pEDOT:PSS). Initially, titania nanotube arrays were produced by the anodization process of Ti substrate. Next, the polymer was potentiostatically deposited onto the thermally annealed nanotube arrays from the electrolyte containing monomer and counter ion. The obtained material was characterized by means of Raman spectroscopy, SEM and photoluminescence spectroscopy. On the basis of electrochemical studies, a radical decrease in the electrode material resistance after conductive polymer deposition was detected. The enhancement in registered current under UV–vis irradiation was almost 4 times higher for a composite with the highest amount of deposited pEDOT:PSS in comparison to pristine titania nanotube array film.
