Abstract

L'invention concerne des milieux poreux, notamment des milieux filtrants, dissipant les charges électriques générées lorsqu'un fluide tel qu'un fluide non polaire passe à travers les milieux poreux. Les milieux poreux comprennent une fibre de verre, polymère ou céramique non conductrice ainsi qu'une fibre polymère conductrice, une fibre de verre ou céramique non conductrice ainsi qu'une fibre revêtue d'un matériau conducteur, une fibre de verre non conductrice ainsi qu'une fibre conductrice imprégnée de métal, une fibre polymère synthétique non conductrice ainsi qu'une fibre revêtue de métal, une fibre polymère naturelle non conductrice et une fibre imprégnée d'un matériau conducteur ou une fibre de verre, céramique ou polymère synthétique non conductrice ainsi qu'une fibre métallique. Un milieu filtrant composite comprend une couche de fibres conductrices ou non conductrices posée sur et liée à un substrat électroconducteur.
