Tetraethyl orthosilicate (TEOS) derived sol-gel films have been utiliz
ed for the electrochemical polymerization of aniline. The presence of
electroactive polyaniline (PANI) within the porous skeleton of the TEO
S sol-gel films has been confirmed using cyclic voltammetry, UV-visibl
e, infrared spectroscopy, and scanning electron microscopic measuremen
ts.
