Abstract: front page image
(EN)There is disclosed a chemiresistor which comprises a non-conducting substrate at least partially coated with an electrically-conductive polypyrrole film, characterised in that the said substrate is a high melting-point, thermoplastic polymer selected from: an aromatic polyetherketone, a polyethersulphone, a polyetherimide, a polyimide and a polyamide. Also disclosed is a method of polymerizing a pyrrole monomer, comprising the step of contacting said pyrrole monomer with an oxidising agent in an aqueous solution, wherein the aqueous solution comprises an organic co-solvent which is at least partially miscible with water. There is also disclosed a process for treating a chemiresistor comprising a non-conducting substrate at least partially coated with an electrically-conductive polypyrrole film, wherein an oxidising agent or an acidic agent is contacted with the surface of the said film.
(FR)Cette invention concerne une chimiorésistance comprenant un substrat non conducteur recouvert au moins en partie d'une pellicule de polypyrrole électriquement conductrice, caractérisée en ce que ledit substrat est constitué par un polymère thermoplastique à point de fusion élevé pris parmi les composés suivants :polyéthercétone aromatique, polyéthersulphone, polyétherimide, polyimide et polyamide. L'invention porte également sur un procédé de polymérisation d'un pyrrole monomère consistant à mettre en contact ledit pyrrole monomère avec un agent oxydant dans une solution aqueuse, laquelle solution aqueuse renferme un co-solvant organique au moins partiellement miscible dans l'eau. L'invention concerne également un procédé de traitement d'une chimiorésistance comprenant un substrat non conducteur recouvert au moins partiellement d'une pellicule électriquement conductrice de polypyrrole, procédé au cours duquel un agent oxydant ou un agent acide est mis en contact avec la surface de ladite pellicule.
