SYNTHESIS, CHARACTERIZATION AND ELECTRICAL-PROPERTIES OF IODINATED POLY(N-VINYLIMIDAZOLE)

Poly (N-vinylimidazole) was synthesized by radical polymerization. The synthesis of this conducting polymer was achieved via iodination befo re doping. Characterization of the product was based on elemental anal ysis, FT-IR spectral analysis and differential scanning calorimetry (D SC) techniques. The long-lasting conductivity of iodinated poly (N-vin ylimidazole) leads us to propose that a more stable charge transfer co mplex was formed between the dopant and polymer. The changes in conduc tivity of iodinated poly(N-vinylimidazole) with time and the temperatu re dependence of its electrical conductivity were also studied.
