HIGH-PURITY PARASTYRENE SULFONIC ACID (SALT); POLYSTYRENE SULFONIC ACID (SALT) USING SAME; DISPERSANT, CONDUCTIVE POLYMER DOPANT, AQUEOUS NANOCARBON MATERIAL DISPERSION AND AQUEOUS CONDUCTIVE POLYMER DISPERSION EACH USING POLYSTYRENE SULFONIC ACID (SALT); AND METHOD FOR PRODUCING POLYSTYRENE SULFONIC ACID (SALT)

摘要

Provided is a novel polystyrene sulfonic acid (salt) which is useful as a dispersant for producing an aqueous dispersion of a nanocarbon material such as a carbon nanotube, graphene or fullerene or an aqueous dispersion of a conductive polymer such as a polythiophene, polypyrrole, polyaniline, polyphenylene vinylene or polyphenylene. A structure-controlled polystyrene sulfonic acid (salt) which is obtained using a high-purity parastyrene sulfonic acid (salt) that contains less impurities such as isomers; a dispersant which contains the polystyrene sulfonic acid (salt) as an active ingredient; an aqueous dispersion of a nanocarbon material or a conductive polymer, which is obtained using the dispersant; and a method for producing the polystyrene sulfonic acid (salt).
