Abstract
Present study investigates the electrical properties of a thin film of poly(9,9-dihexyl fluorenyl-2,7-diyl): poly(2-methoxy-5-(2-ethylhexyloxy)-1, 4-phynylenevinylene) (PFO:MEHPPV) polymer blends using impedance spectroscopy in the frequency range of 0.1 Hz–1 MHz. From the analysis of complex impedance data, we found that in the PFO: MEH-PPV polymer blend structure, the best way to describe the conductivity is a single relaxation process. An improved conductivity of the blended PFO polymer thin film was obtained on the basis of different concentrations of MEH-PPV. Cole-Cole plots for blend devices are characterized with a single network of parallel combination of resistor RP and capacitor CP with series resistance RS. The resistance RP decreases when a bias is applied, however the capacitance CP does not change substantially.
