Abstract

L'invention a pour objet un film chauffant polymère à résistance à coefficient de température positif, CTP, (1) comprenant une couche polymère électroconductrice à résistance CTP, caractérisé par le fait que la couche polymère électroconductrice à résistance CTP est une couche de polymère électroconductrice à résistance CTP (2) comprenant une matrice de polymère thermoplastique dans laquelle sont réparties des charges conductrices, le film chauffant polymère à résistance CTP (1) comprenant en outre une première électrode surfacique (3) recouvrant l'une des faces de la couche de polymère électroconductrice à résistance CTP (2) et une seconde électrode surfacique (4) recouvrant l'autre opposée des faces de la couche de polymère électroconductrice à résistance CTP (2). L'invention a également pour objet un procédé de fabrication d'un tel film chauffant polymère à résistance CTP (1).
