Abstract

Méthode de fabrication d'un élément électret par bombardement électrique. L'élément est sensibilisé dans une enceinte et se trouve en contact avec un liquide de faible tension de vapeur saturante dont la rigidité diélectrique est supérieur à celle de l'air raréfié. Application à la fabrication de rubans électrets.
