A process and materials made by the process which includes a bicomponent fiber, made of a nonconductive first component, including a first fiber-forming polymer selected from the group consisting of polyethylene terephthalate, nylon 6, nylon 6,6, cellulose, polypropylene cellulose acetate, polyacrylonitrile and copolymers of polyacrylonitrile; a conductive second component, including carbon particles and a second fiber-forming polymer selected from the group consisting of polyethylene terephthalate, nylon 6, nylon 6,6, cellulose, polypropylene cellulose acetate, polyacrylonitrile and copolymers of polyacrylonitrile; and a conductive third component, including a polymer selected from the group consisting of polypyrrole and polyaniline, said polymer formed in situ and being interspersed among at least a portion of the carbon particles of the second component.

L'invention concerne un procédé de fabrication et les matériaux fabriqués selon ce procédé. Ces matériaux comprennent une fibre à multicomposants, fabriquée à partir: d'un premier composant non conducteur, renfermant un premier polymère constituant la fibre, choisi dans le groupe composé par le polyéthylène téréphtalate, le nylon 6, le nylon 66, la cellulose, l'acétate de cellulose de polypropylène, le polyacrylonitrile et les copolymères de polyacrylonitrile; d'un deuxième composant conducteur, renfermant des particules de carbone et un second polymère constituant la fibre, choisi dans le groupe composé par le polyéthylène téréphtalate, le nylon 6, le nylon 66, la cellulose, l'acétate de cellulose de polypropylène, le polyacrylonitrile et les copolymères de polyacrylonitrile; et d'un troisième composant conducteur, renfermant un polymère choisi dans le groupe composé par le polypyrrole et la polyaniline, ce polymère étant formé in situ et espacé le long d'au moins une partie des particules de carbone dudit deuxième composant.
