Enhancement of the thermoelectric performance for DTC-based polymervia N-octyl substitution
Focusing on the impact of carrier concentration and mobility on thermoelectric parameters, a good design strategy was successfully implemented on dithiophene cyclopentadiene (DTC)-based organic polymer materials. In this work, two alternative copolymersP(DTCTBT)andP(DTPTBT)were prepared from DTC andN-octyl substituted DTC monomers, respectively. Thus, the equilibrium between electrical conductivity and Seebeck coefficient was realized by means of the dual increase of the carrier concentration and mobility. In comparison with the dopedP(DTCTBT), the dopedP(DTPTBT)film exhibited a much higher carrier concentration and mobility, owing to the rich electron delocalization and highly crystalline texture, which resulted in an excellent electrical conductivity (155 S cm?1) and a moderate Seebeck coefficient. The power factor ofP(DTPTBT)(3.4 muW m?1K?2) was over 20 times larger than that ofP(DTCTBT)(0.16 muW m?1K?2) at room temperature. With the temperature increasing, a highest power factor of 39.5 muW m?1K?2was detected forP(DTPTBT), which can be considered as a superior value among those of the conjugated polymer materials reported in previous literature.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 52409-22-0, you can also check out more blogs about52409-22-0
