Abstract
The invention relates to a process for the preparation of a porous material layer covered with an electronically conductive polymer and to the product obtained by this process. This process consists of placing the layer (1) on a support sheet (3) optionally having roughnesses or unevennesses (4), applying to the layer a polymerization solution comprising a monomer (pyrrole), an oxidizing agent (FeCl.sub.3) and a doping agent (naphthalene disulphonic acid salt) using nozzles (6). The assembly is then wound up to form a composite roll (11), which is then immersed in the same polymerization solution for an adequate time to form a uniform, conductive polymer deposit (polypyrrole). It is thus possible to obtain conductive textiles with surface resistances of 5 to 20 Ohm.sup.2.
