Conjugated polymers have recently emerged as a new class of thermoelectric (TE) materials, thus opening new avenues for harvesting thermal energy by scalable and inexpensive processes. However, their electrical conductivities need to be improved and molecular doping is one of the most effective ways. Although the doping can be performed by simple one-step solution mixing method instead of sequential doping, most molecular dopants and doped polymer solutions often exhibit poor solubilities. This presentation will introduce a series of studies about the fabrication of solution-mixed organic TE materials to overcome the aforementioned issues and thus to obtain excellent TE properties. The resulting doped polymer films exhibit outstanding TE properties with the record-high power factor and ZT among the reported p-type soluble conjugated polymers. At the end, some conceptual approaches to improve the mechanical (stretching/self-healing/adhesion) properties will also be briefly introduced. |
