COMPOSITION CONTAINING A POLYMER OR COPOLYMER OF 3,4-DIALKOXYTHIOPHENE AND NON-AQUEOUS SOLVENT |
摘要 |
<p>A method for preparing a composition containing between 0.08 and 3.0% by weight of polymer or copolymer of a 3,4-dialkoxythiophene in which the two alkoxy groups may be the same or different or together represent an optionally substituted oxy-alkylene-oxy bridge, a polyanion and at least one non-aqueous solvent from a dispersion of the polymer or copolymer of (3,4-dialkoxythiophene) and the polyanion in water which is prepared in the substantial absence of oxygen, comprising in the following order the steps of: i) mixing at least one of the non-aqueous solvents with the aqueous dispersion of the polymer or copolymer of (3,4-dialkoxythiophene) and the polyanion; and ii) evaporating water from the mixture prepared in step i) until the content of water therein is reduced by at least 65% by weight; a printing ink, printing paste or coating composition, capable of yielding layers with enhanced conductivity at a given transparency, prepared according to the above-described method; a coating process with the coating composition thereby producing a layer with enhanced conductivity at a given transparency; and a printing process with the printing ink or paste.</p> |
