METHOD OF INCREASING POLYANILINE CONDUCTIVITY WITH IONIC SURFACTANTS

摘要

PURPOSE: A method of increasing polyaniline conductivity with ionic surfactants is provided to produce not only polyaniline that has a surprisingly high conductivity, but also a composition comprising a polyaniline salt of an organic acid in which the polyaniline has been processed into a useful from such as a film, coating, fiber or the like. CONSTITUTION: The conductivity of a polyaniline composition can be increased upon contacting the polyaniline with an ionic surfactant. The surfactant or surface-active agent is a compound that tends to locate at the interface between two phases and reduces the interfacial tension. The surfactant can reduce surface tension, i.e. the liquid/air interfacial tension, when dissolved in water or other polar solvent, or interfacial tension between two liquids or between a liquid and a solid. A polyaniline salt has been processed into useful forms because of the polyaniline composition starting material being highly soluble in any of a number of carrier solvents. Such films and coatings are continuous in that the polyaniline salt is substantially uniformly dispersed throughout the film.
