ABSTRACT:
Disclosed is a novel method for obtaining conductive polymers enabling their conductive to be increased and thermally stabilized. The polymers are obtained by oxidative chemical process in the presence of a codopant, the anions of which are more stable than the oxidating anions. The synthesis of the polymer is furthermore followed by a thermal treatment operation by which the conductivity of the material obtained is stabilized. Application: microwave absorbents.
