Pseudo in situ construction of high-performance thermoelectric composites with a dioxothiopyrone-based D-A polymer coating on SWCNTs.Organic polymer/inorganic particle composites with thermoelectric (TE) properties have witnessed rapid progress in recent years.  In this study, we first demonstrated a simulated in situ coagulation strategy for construction of high-performance thermoelectric materials by utilizing single-walled carbon nanotubes (SWCNTs) and a new D-A polymer TPO-TTP12 that was synthesized via incorporating dioxothiopyrone subunit into a polymeric chain.  It was proven that the preparation methods have a significant influence on thermoelectric properties of the TPO-TTP12/SWCNT composites.  The in situ prepared composite films tend to achieve much better thermoelectric performances than those prepared by simply mixing the corresponding polymer with SWCNTs.  This indicates that the dioxothiopyrone moiety is a promising building block for constructing thermoelectric polymers, and the simulated in situ compositing strategy is a promising way to improve TE properties of composite materials.
