Polyanilines: Synthesis, Conformational Structures, and Applications

I. INTRODUCTION A polymeric material that possesses the electronic, magnetic, electrical, and optical properties of a metal while retaining the processibility and mechanical properties usually associated with a conventional organic polymer is called a conducting polymer. Since the first demonstration of metallic conductivity in AsF5-doped polyacetylene by MacDiarmid and co-workers in 1977 [1] , conducting polymers have become the main part of a larger class of materials commonly known as synthetic metals.
