Acqueous composition comprising a conductive polymer and use thereof

Abstract

Aqueous composition comprising: from 0.5% by weight to 5% by weight, preferably from 1% by weight to 4% by weight, with respect to the total weight of said aqueous composition, of at least one conductive polymer; from 1% by weight to 100% by weight, preferably from 2% by weight to 10% by weight, more preferably from 15% by weight to 50% by weight, with respect to the total weight of said at least one conductive polymer, of at least one cellulose ether. Said aqueous composition may advantageously be used as a printable ink or printable paste in various techniques such as, for example, screen printing, gravure printing, flexographic printing, spray coating, slot die coating, spin-coating, ink-jet printing. Preferably, said aqueous composition may advantageously be used as a printable paste for screen printing. More particularly, said aqueous composition may be used for the preparation of electrically organic conductive layers, even more particularly for the preparation of electrically organic conductive layers used in photovoltaic cells (or solar cells), in printable electronics, in organic light-emitting diodes (OLEDs), in touch screens, in antistatic coatings.
