Abstract

 INTRODUCTION: THE NANOCOMPOSITE FORM OF CONDUCTING POLYMERS HAS ATTRACTED SPECIAL ATTENTION FOR THEIR UNIVERSAL APPLICATIONS IN DRUG-DELIVERY SYSTEMS, PLASTIC TRANSISTORS, AND IN MICROWAVE COMPONENTS AFTER COATING WITH METAL, ELECTRONIC AND ELECTRO-OPTICAL DEVICES.PAN IS ONE OF THE MOST USEFUL CONDUCTING POLYMERS BECAUSE OF ITS EASE OF SYNTHESIS AND ENVIRONMENTAL STABILITY. IT ALSO HAS A WIDE RANGE OF ELECTRICAL PROPERTIES WHICH CAN BE EASILY CONTROLLED BY CHANGING ITS OXIDATION AND PROTONATION STATES. HOWEVER, THERE ARE STILL MANY UNRESOLVED PROBLEMS CONCERNING THE STRUCTURES AND PROPERTIES OF PAN BECAUSE OF THE COMPLEXITIES IN ITS MOLECULAR STRUCTURE, DUE TO SYNTHESIS CONDITIONS.IMPROVEMENT OF THESE MATERIAL PROPERTIES CAN BE ACHIEVED EITHER BY FORMING COPOLYMERS, BY FORMING CONDUCTIVE POLYMERIC COMPOSITES.
