Study of Some Electrical Properties of poly alpha naphthyle acrylate doped with Ioden(I2)

Abstract

The electrical properties investigation for poly alpha naphthyle acrylate doped with Ioden (I2) films was carried out for films prepared by cast method.Conduction processes were analysed through measuring (Current – Voltage) and (Conductivity – temperature) relationships in the voltage and temperature ranges (1-120) V and (308 -373) K respectively. The resistance of the doped films is found to have a negative thermal coefficient. The activation energy at temperature (308 -373)K was about (0.6)eV is found from the ohmic region of the dark (current – voltage) characteristic. The conductivity at temperature 308 was equal to 5.57×10-12 (S.cm-1).The deviation from ohm's law has been analysed in term of the available conduction theories, ionic conduction mechanism was concluded.
