We have studied the electrical transport properties of a new polymer blend consisting of polyoctylthiophene (POT) melt processed into a polyethylenevinyl-acetate (EVA) matrix. The EVAPOT blend doped with FeCl3 has a room temperature dc conductivity σdc (300K) varying from 10−8 Ω−1cm−1 to 1Ω−1cm−1 with increasing doping. The temperature dependence of , especially in highly conducting samples where the conduction can be described by the granular metal model. This conclusion is supported by the small metallic thermoelectric power which varies linearly with temperature.
