ABSTRACT:
The present invention is directed to vibrational methods of fabricating electrically conducting polymers and precursors thereof in which the polymer chains are deaggregated. Such deaggregated conducting polymers and precursors thereof exhibit better solution processability and higher electrical conductivity than do the corresponding aggregated polymers. The polymers in the non-doped precursor form or in the conducting form in solution or during the polymerization process are exposed to ultrasound and shear mixing. Due to this treatment, the chains become deaggregated. Furthermore, ultrasound and shear mixing is used during the doping of the precursor polymers. This treatment allows more uniform doping, enhanced solubility, and higher electrical conductivity. The solutions treated with ultrasound/shear mixing are subsequently processed into a structural part, a film, or a fiber.
