Electrochemical growth of polyaniline in porous sol-gel films

Tetraethyl orthosilicate (TEOS) derived sol−gel films have been utilized for the electrochemical polymerization of aniline. The presence of electroactive polyaniline (PANI) within the porous skeleton of the TEOS sol−gel films has been confirmed using cyclic voltammetry, UV−visible, infrared spectroscopy, and scanning electron microscopic measurements.
