Abstract :
This paper describes the doping influence of the ionic dye, rhodamine 6G (R6G), on the electric current of VDF-TrFE copolymer induced by irradiation with a TEA CO2 laser. The current of the undoped sample increases rapidly at poling fields over 0.4 MV/cm, and that of the doped one has a lower rapid increasing point. X-ray diffraction, infrared spectra and dielectric constant measurements of undoped and doped samples are reported. The qualitative analysis shows that the current is affected by ionic dye doping
