Title
(EN) LIQUID COMPOSITIONS COMPRISING PARTICLES OF A CONDUCTIVE POLYMER AND AN ORGANIC SOLVENT FORMING AN AZEOTROPE WITH WATER
(FR) COMPOSITIONS LIQUIDES COMPRENANT DES PARTICULES D'UN POLYMÈRE CONDUCTEUR ET UN SOLVANT ORGANIQUE FORMANT UN AZÉOTROPE AVEC DE L'EAU
Abstract
(EN)
The present invention relates to a liquid composition comprising i) particles comprising a complex of a polythiophene and a polyanion; ii) a liquid phase, wherein the liquid phase comprises iia) water and iib) at least one organic solvent having -a boiling point, determined at a pressure of 1013 mbar, in the range from 110 to 250°C and -a solubility in water, determined at 25°C,of at least 10 wt.-%, wherein the liquid phase is an azeotrope or is capable of forming an azeotrope. The invention also relates to a process for the preparation of a layered body, to the layered body obtainable by such a process and to the use of a liquid composition.
(FR)
La présente invention concerne une composition liquide comprenant i) des particules comprenant un complexe d'un polythiophène et d'un polyanion ; ii) une phase liquide, la phase liquide comprenant iia) de l'eau et iib) au moins un solvant organique présentant - un point d'ébullition, déterminé à une pression de 1013 mbar, dans la plage de 110 à 250 °C et - une solubilité dans l'eau, déterminée à 25 °C, d'au moins 10 % en poids, la phase liquide étant un azéotrope ou étant apte à former un azéotrope. La présente invention concerne également un procédé de préparation d'un corps stratifié, le corps stratifié pouvant être obtenu par ce procédé, et l'utilisation d'une composition liquide.
