Abstract:A facile method for chemical doping of conducting polymers is demonstrated with an ionic liquid containing FeCl4
- anions as the oxidizing agents. A drop of the ionic liquid on the film of a typical semicrystalline polymer immediately changed the room temperature conductivity to 500 S/cm. The highly conductive state originated from both the high doping level and the high crystallinity of the doped film, as confirmed by optical absorption and X-ray diffraction measurements, respectively.
