以聚3-己基噻吩（3-hexylthiophene，GNs）为原料，在氯仿中进行氧化聚合，制备了石墨烯纳米片/聚3-己基噻吩（GNs/P3 HT）复合材料。用X射线衍射和傅里叶变换红外光谱分析了复合材料的物相组成。在室温下测试了不同GNs含量的冷压复合材料的热电性能。随着GN负载量从0增加到30重量%，复合材料的电导率从接近10（-6）急剧增加到接近1.2 S/cm，而塞贝克系数从33.15 μ V/K略微增加到35.46 μ V/K。最高的功率因数（类似于0.16 μ W m（-1）K-2）在30 wt.% GNs/P3 HT复合材料。(C)2012爱思唯尔有限公司版权所有。
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.
