- Conductive fibers are also of interest in applications where the heating effect is not sought, for their antistatic properties, in particular in the manufacture of aeronautical or automotive parts or for the electromagnetic shielding of electronic equipment, for example to dissipate electrical charges resulting from friction, induced in particular during the circulation of a fluid in a thermoplastic pipe.
- the conductive fibers known in the prior art include: metallic wires, which have the disadvantage of being heavy and liable to oxidize,
- the intrinsically conductive polymer fibers which are poorly resistant to washing and are not very stable, insofar as they are sensitive to oxidation and also to heat released by the Joule effect which can chemically degrade (for example crosslink) the polymer and / or altering its mechanical properties beyond a certain temperature, - the polymer fibers made conductive by deposition of conductive particles on their surface, such as silver fibers, whose coating is likely to deteriorate by friction and wear, and
