Process for modifying electroconductive polymers using ion exchange

摘要

In electrically conducting polymers in their oxidized (doped) form, which are known per se, the anions can be exchanged in any desired manner, if the polymer in solution is brought into contact with a salt containing the anion to be exchanged and the solution equilibrium is established, taking account of the solubility product of the salts present. In this manner, the properties of the electrically conducting polymers can be adapted to different purposes.
