Graphene nanosheets/poly(3-hexylthiophene) (GNs/P3HT) composites were prepared by oxidative polymerization of 3-hexylthiophene in a GNs dispersed chloroform solution. The phase composition of the composite materials was analyzed by X-ray diffraction and Fourier transform infrared spectra. The thermoelectric properties of the cold pressed composite pellets with different GNs loadings were measured at room temperature. As the GNs loading increased from 0 to 30 wt.%, the electrical conductivity of the composites dramatically increased from similar to 10(-6) to similar to 1.2 S/cm while the Seebeck coefficient slightly increased from 33.15 to 35.46 mu V/K. The highest power factor (similar to 0.16 mu W m(-1) K-2) was obtained in the 30 wt.% GNs/P3HT composite material. (C) 2012 Elsevier B.V. All rights reserved.
