PROCESS FOR THE PRODUCTION OF A POROUS MATERIAL WEB COATED WITH AN ELECTRONICALLY CONDUCTIVE POLYMER AND PRODUCT THUS OBTAINED

摘要

This invention discloses a process for the production of a web of porous material coated with an electronically conductive polymer and product made according to this process. The process comprises placing the web (1) on a backing sheet (3) optionally with surface irregularities (4), and applying on the web, by means of nozzles (6), a polymerization solution containing a monomer (pyrrole), an oxidizing agent (FeCl3) and a doping agent (naphthalenedisulfonic acid salt). The assembly is then rolled up to form a composite reel (11) which is thereafter immersed in the same polymerization solution for a length of time sufficient to form a uniform conductive polymer (polypyrrole) deposit. Conductive textiles with unit area resistances of 5 to 20 OMEGA /square can thus be obtained.
