摘要
The present invention discloses a water-soluble self-acid- doped polyaniline, and its sodium salt, which can be cast into free- standing films from their aqueous solutions. A process for preparing a water- soluble self-acid-doped polyaniline is also disclosed, which comprises reacting a polyaniline with a strong base to convert the amino nitrogen thereof to anionic nitrogen; reacting sultone with the anionic nitrogen to form a side chain alkanesulfonic acid group; doping with protonic acid to form precipitate; dissolving (undoping) the precipitate in an alkaline aqueous solution; removing excess alkali from the alkaline aqueous solution; and contacting the resulting aqueous solution with a H. sup.+ - type ion exchange resin. Moreover, an aqueous solution of the present water-soluble self-acid-doped PAn can be easily mixed with an additional water soluble polymer or polymer emulsion, which can then be cased into a polymer blend film having improved mechanical properties and coupling strength to a substrate.
