A 316 STEEL ELECTRODE COATED WITH POLYCARBONATE FOR ELECTROPOLYMERIZATION OF ANILINE

摘要

In this study, homogenous and flexible conductive polymer films with improved mechanical properties were obtained by the electrochemical polymerization of aniline on polycarbonate-coated 316 steel electrodes. The optimal thickness of polycarbonate coating was found to be 20 mu m in order to obtain free-standing, high-quality conducting films. The polyaniline/polycarbonate films obtained on 316 steel electrodes were more homogenous than those obtained on platinum electrodes. The maximum conductivity was observed for 10% polyaniline content; increasing the polyaniline content did not affect the conductivity to a significant extent. The films were found to be a suitable sensor against ammonia gas in a concentration range of 0.1-1.0%. (C) 1997 John Wiley & Sons, Inc. [References: 29]
