The invention relates to a method for production of films or sheets, made from thermoplastic plastics with electrically-conducting coatings, by means of the following method steps: a) single-sided coating of a support film made from a thermoplastic plastic with a paint composition, made from silicon containing inorganic semiconductor particles, b) extrusion of a fused web of a thermoplastic plastic, c) bringing into contact the coated side of the support film with the fused web of the thermoplastic plastic in the rolling gap of the polishing stack, d) removal of the support film from the composite, whereby the coating on the support film remains on the extruded thermoplastic plastic and e) optional cooling of the plastic web to ambient or room temperature. The invention further relates to the extruded and coated films and sheets and the uses thereof.
L'invention concerne un procédé de fabrication de pellicules ou plaques en plastique thermoplastique présentant un revêtement électroconducteur. Ledit procédé consiste a) à revêtir unilatéralement une pellicule support en plastique thermoplastique présentant une composition de vernis à base de silicium, contenant des particules de semiconducteurs anorganiques ; b) à extruder une barre de coulée d'un plastique thermoplastique ; c) à mettre en contact le côté revêtu de la pellicule support et la barre de coulée du plastique thermoplastique extrudé dans l'espace entre les cylindres de la lisseuse ; d) à retirer la pellicule support du composite, le revêtement de la pellicule support restant en place sur le plastique thermoplastique extrudé ; et, e) à refroidir éventuellement la bande de plastique à température ambiante. L'invention concerne également les pellicules et plaques extrudées et revêtues, et leurs utilisations.
