Title: Preparation and properties of polymer thermoelectric materials, polymer/SWCNT thermoelectric composites, and organic small molecule/SWCNT thermoelectric composites
Abstract:
Thermoelectric (TE) materials can directly convert heat to electricity based on the Seebeck effect. Conductive polymers and organic small molecules hold great potential for harvesting low-grade thermal energy which is beneficial for highly efficient energy utilization and environmental protection. TE composites with enhanced thermoelectric properties are realized by engineering nanostructures of conductive polymers, compositing conductive polymers and single-walled carbon nanotubes (SWCNTs), and compositing organic small molecules (OSMs) with SWCNTs. In this presentation, flexible conductive polymer/SWCNT thermoelectric composites including polypyrrole/SWCNT composites, poly(3,4-ethylenedioxythiophene)/SWCNT composites, poly(3,4-ethylenedioxythiophene)/Te/SWCNT composites, poly(3,4-ethylenedioxythiophene)/polyethylene/SWCNT, polyaniline/SWCNT composites, and poly(aniline-co-pyrrole)/SWCNT composites, nanostructured polypyrrole, and thiophene derivative/SWCNT composites are introduced. The SWCNT-containing thermoelectric composites combine high electrical conductivity of SWCNTs and good flexibility plus low thermal conductivity of conductive polymers or OSMs, hence manifesting their emerging applications in heat utilization and sensing scenario.
