    摘要: A method is provided for the preparation of a conductive composition containing a polymerized aromatic amine wherein the aromatic amine is oxidatively polymerized in an acidic aqueous medium in the presence of an oxidizing agent, a doping agent and an aromatic polyalkyleneoxide in an amount sufficient to stabilize the resulting composition. Preferably, the aromatic amine is aniline or a substituted aniline. Compositions produced by such method are also disclosed. These compositions are useful for treating various substrates to make such substrates conductive.

    摘要: A process for heat treating substituted and/or unsubstituted polyaniline which has been doped with a relatively non-volatile acid is provided. Subjecting polyaniline to temperatures of between 70.degree. C. and 200.degree. C. for a moderate amount of time dramatically lowers the resistance, and therefore increase the conductivity, of the polyaniline. Heat treatment of polyaniline may be advantageously combined with a subsequent rinsing step to produce a sample which has superior stability and good conductivity.
