Synthesis and Characterization of Some Conducting Polymers and Their Complexed Compounds

Abstract

The chemical co-polymerization of aniline with o-anthranilic acid (AA) to form copolymer films has been made in aqueous hydrochloric acid medium. Poly vinylcarbazole (PVK) was prepared by free radical mechanism. The copolymer (AA) and polymer (PVK) were reacted with KI respectively, to produce a complex compounds. Also, the complex of copolymer (AA) with NaOEt was prepared. The conductivity, IR spectra and the thermal gravimetric analysis of these polymers and their complexes were measured and discussed. It was found that, the specific electrical conductivity (σ) of the copolymer (AA) in presence of NaOEt increases with increase in temperature, whereas decreases with complex of copolymer (AA) +KI. The electrical properties of the PVK were enhanced upon reacting it with KI.
