Abstract

Des films de polyfluorure de vinylidene ont ete irradies aux ions lourds rapides. Les ions energetiques en traversant le polymere, induisent la creation de radicaux libres localises dans la trace latente. Ces radicaux sont capables d'amorcer le greffage radiochimique du methacrylate de methyle. Nous avons etudie l'influence des parametres d'irradiation tels que la dose absorbee, la nature de l'ion et le pouvoir d'arret electronique. Nous avons mis en evidence l'influence de l'inhibiteur et le role de la phase cristalline du polymere substrat sur le radiogreffage.
