Recent advances in organic polymer thermoelectric composites
Thermoelectric materials can realize the direct energy conversion between heat and electricity, having diverse applications in energy harvesting (especially for waste heat and low-grade heat) and local cooling and sensing. In recent years, organic polymer thermoelectric composites have received extensive attention and have experienced a rapid development because of their low densities, low thermal conductivities, high flexibilities, and the synergistic combination of the advantages of both constituents. This review covers the recent advances in organic polymer thermoelectric composites. Herein, their preparation strategies have been discussed. In addition, the non-conducting polymer-based composites, ternary composites, and the devices have also been discussed. Finally, an outlook on future investigations is provided.
