FIELD: waterless conducting solutions.
SUBSTANCE: invention, in particular, relates to preparation of solutions containing optionally substituted polythiophenes in waterless or low-water organic solvents, to solutions themselves, an to their technical applications. Solution preparation method of invention is characterized by that to an aqueous solution of ionic complexes polythiophene+An+ (wherein polythiophene+ denotes polymers containing positively charged repetitive units of formula I) is added a water-miscible organic solvent or a water-miscible mixture of organic solvents. Resulting mixture is then at least partially freed of water. Invention also includes solutions of ionic complexes prepared according to above-indicated method. Further included are also: method of imparting electrical conductivity to substrates, method of imparting antistatic properties to substrates, method of preparing solid electrolytes in solid condensers, and method of manufacturing electroluminescent devices.
EFFECT: extended choice of waterless conducting solutions for a variety of technical applications.
