DC conductivity measurements of 1.4-cis-polybutadine doped with sexiphenyl were carried out. The aim of these measurments was to study conduction mechanisms, i.e. the methods of injection of charge carriers into the bulk of the material and transport properties. Roentgenography measurements were carried out to study structure of the solid as well as the phase transitions. As this work presents a portion of our investigations they were restricted to the results obtained for a layer having thickness d = 2.4 µm with gold and aluminium electrodes coupled. The temperature was chanbed from 127 K to 366 K. The range of voltages applied was 0 to 120 V. 1.4-cis-polybutadiene consisting of 96% cis-and 4% trans-form was purchased from Philips Pertoleum Corp. Sexiphenyl was purchased from Tokyo Kasei Kogyo Co. Ltd. A correlation was observed between internal structure of the material and its electrical properties. It was found that DC conductivity can be described in terms of Poole-Frankel effect, high-field hopping and Richardson-Schottky (R-S) effect. Determined activation energies are ranging from 0.035 eV to 0.18 eV.
