Synthesis and Physical Properties of Highly Sulfonated Polyaniline

摘要: Sulfonated polyaniline (SPAN) is a self-doped conducting polymer. It has high water solubility and novel pH-dependent DC conductivity that of interest for fundamental science also applications in such areas as rechargeable battery pH control technologies. We report here the extensive characterization details synthesis new form sulfonated (LEB-SPAN) which shows or significantly improved chemical physical properties. LEB-SPAN sulfur to nitrogen ratio (S/N) ∼0.75, 50% larger than previously reported EB-SPAN, S/N ∼0.50. This change composition leads significant alteration properties including an order magnitude increase room temperature ∼1 S·cm-1, nearly double water, completely different dependence oxidation potential (E1/2). For unaffected by over range 0 ≤ 14, strikingly from behavior both pare...
