Paper Abstract

The standard poling procedure of a PVDF biaxially oriented film implies for simplicity of the equipment, the combined application of a DC electric field between the metallic electrodes deposited on both faces on the film, and a temperature ranging between the ambiant and the Curie point. So far, no scientific approach has been advanced to justify the values of the poling parameters : the applied voltage Vp, the temperature Tp, the duration t , usually adopted during the poling. The interdependence between the three parameters effEcts should be considered, as the maximum dipole orientation is achieved for an applied voltage value depending on the other two parameters. (1000 V for 90°C and 30 mn, whereas 1200 V for 70°C and 30 mn in our experiments).
