L'influence de la température de polarisation sur l'effet piézo-électrique dans les films de PVDF préparés à partir d'une solution, a été étudiée. Les résultats obtenus ont été discutés sur la base de la dépendance de la constante piézo-électrique (e31) et le module piézo-électrique (d33) en fonction du taux de cristallinité pour différents modes de vibration. La diminution de taux de cristallinité avec l'augmentation de température de polarisation a été observée en se basant des spectres des rayons X
