Conductivité Electronique et Propriétés Chimiques de Polyanilines Oligomères

Products obtained by a simple method of preparing emeraldines have been studied with respect to their acidity, redox, and complex formation properties: analysis of neutralization curves with strong bases relating to aqueous suspensions of emeraldines show these compounds to behave as two different acids, a strong and a weak one; analysis of quantitative characteristics of these curves indicates complex formation with sulfate, chloride, and formiate anions; the interaction between different redox couples and emeraldines in aqueous suspension and in colloid solution has been investigated

  • This study of chemical properties of aniline oxidation products establishes conditions of preparation for different derivatives pertaining to the polyaniline family
  • The conductivity varies with the hydration and acid–base parameters of different derivatives; its value is very high for an organic material and ranges from 10 to 10−4 ohm−1 cm.−1 depending on the values of the parameters indicated
