Carbon nanotubes (CNTs) were dispersed in polycarbonate (PC) matrix by solution method. Then the obtained PC/CNT flocculation was used to prepare the flexible thermoelectric PC/CNT composites by compression molding. The fractured morphology of PC/CNT composite suggested that CNTs are distributed homogenously in the PC matrix. Besides, with increasing CNT contents, the electrical conductivities increase dramatically whereas the Seebeck coefficients nearly remain constant. This leads to the rapid increasing trend of power factor with CNT content for the PC/CNT composites. The maximum power factor is 4.6 μW·m^-1·K^-2.
