Recently, conjugated polymers have emerged as a new class of thermoelectric (TE) materials, opening new avenues for harvesting thermal energy by inexpensive and scalable routes. Here, I present 3 different approaches to improve the TE and mechanical properties of conjugated polymer-based TE materials: 1) molecular doping of conjugated polymers via simple solution mixing, 2) efficient debundling of few-walled CNTs by wrapping with conjugated polymers, and 3) nanostructuring of conjugated polymers in a thermoplastic elastomer matrix. The first two parts of this presentation will focus on how to improve the TE properties of the polymers and their composite films as well as the performance of flexible TE generators. In the last part, two novel designing strategies of TE materials will be introduced to realize self-healable and stretchable organic TE materials and to minimize the thermal resistance between the heat sources and the TE material. |
