ABSTRACT:
Polythiophene may be processed using a method including providing a composition including the polythiophene and a liquid including at least one hydrocarbon having at least 6 carbon atoms; heating the composition to a temperature of at least about 50° C.; and separating solid polythiophene from the heated composition. Alternatively, the method may include providing a composition including polythiophene and an organic liquid; heating the composition to dissolve a portion of the polythiophene in the organic liquid; and separating solid polythiophene from the heated composition.
