Abstract

DIAMOND NANOPARTICLES (DNP) MUCH ATTENTION HAVE ACHIEVED DUE TO THEIR UNIQUE PROPERTIES AND INEXPENSIVE LARGE SCALE SYNTHESIS WITH NANO-SIZE DISTRIBUTION [1]. ON THE OTHER, MORE RECENTLY, THE NANOCOMPOSITE MATERIALS HAVE BEEN WIDELY USED AS A NEW FORM OF SUPPORT FOR ELECTROCATALYSTS AND BIOSENSOR, SENSOR, AND THERMAL APPLICATIONS [2]. IN THIS WORK POLYPYRROLE /DIAMOND NANOPARTICLES (PPY/DNP) NANOCOMPOSITE COATING WAS SYNTHESIZED ON MILD STEEL VIA CYCLIC VOLTAMMETRY TECHNIQUE. THE ULTRASONIC IRRADIATION WAS USED FOR DISPERSING THE DNP IN POLYMERIZATION SOLUTION. THE PREPARED NANOCOMPOSITE COATINGS WERE FOUND TO BE NANO-COLLOIDAL, AND VERY ADHERENT. X-RAY DIFFRACTION AND SEM (FIG.1) IMAGES CONFIRMED THE PRESENCE OF THE NANOPARTICLES IN PPY MATRIX. THE CORROSION PERFORMANCE OF THE COATINGS WAS STUDIED IN 3.5% NACL CORROSIVE SOLUTION BY ELECTROCHEMICAL IMPEDANCE SPECTROSCOPY (EIS) AND POLARIZATION METHODS. THE RESULTS OBTAINED SHOWED THAT THE INCORPORATION OF DNP SIGNIFICANTLY ENHANCED THE CORROSION PROTECTION PERFORMANCE OF THE PPY FILMS IN CORROSIVE MEDIUM. EIS AND POLARIZATION MEASUREMENTS INDICATED THAT THE COATING RESISTANCE AND CORROSION RESISTANCE VALUES FOR THE PPY/DNP NANOCOMPOSITE COATING WERE MUCH HIGHER THAN THAT OF PURE PPY-COATED ELECTRODE.
