Aluminum as a suitable Substrate for the deposition of conducting polymers: application to polyaniline and enzyme-modified electrode

Electrochemical polymerization of aniline onto an aluminum substrate electrode was studied. The obtained results were compared to those obtained with Pt substrate electrode. It indicates the possibility of aluminum for using as substrate electrode for electropolymerization. Moreover, the electrochemical polymerization of aniline on a passivated Al electrode was studied. The stability of the three different electrodes were studied and compared during potential cycling. Incorporation of glucose oxidase as a typical enzyme into the polymer films was investigated to prepare an enzyme-modified electrode. The activity of the enzyme incorporated into the polyaniline films formed on different substrate electrodes was also discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
