Conducting Polymer and Its Nanocomposites with Thermoelectric Properties†

With the development of modern science and technology and the increasingly serious environmental crisis, the thermoelectric materials and their resulting devices have attracted considerable attention. Compared to inorganic thermoelectric materials, organic polymer are light weight, flexibility, low thermal conductivity and solution-processablethermoelectric materials that become the focus in this field. Currently, the theoretical and experimental studies have proved that thermoelectric materials with low dimension would exhibit good thermoelectric properties for the practical application. Here, we highlight recent work from different laboratories, including our own, toward the design and the characterization of low-dimension polymer thermoelectric materials, with a particular emphasis on the conducting polymers.
