Enhancing the thermoelectric performance through the mutual interaction between conjugated polyelectrolytes and single-walled carbon nanotubes
文献摘要：
We present a method of constructing composites composed of conjugated polyelectrolytes (CPEs) and single-walled carbon nanotubes (SWCNTs) to obtain a high-performing flexible thermoelectric generator.In this ap-proach,three kinds of polymers,namely,poly[(1,4-(2,5-didodecyloxybenzene)-alt-2,5-thiophene](P1),poly[(1,4-(2,5-bis-sodium butoxysulfonate-phenylene)-alt-2,5-thiophene](P2),and poly[(1,4-(2,5-bis-acid butoxysulfonic-phenylene)-alt-2,5-thiophene](P3) are designed,synthesized and complexed with SWCNTs as thermoelectric composites.The elec-trical conductivities of the CPEs/SWCNTs (P2/SWCNTs,and P3/SWCNTs) nanocomposites are much higher than those of non-CPEs/SWCNTs (P1/SWCNTs) nanocomposites.Among them,the electrical conductivity of P2/SWCNTs with a ratio of 1∶4 reaches 3686 S·cm-1,which is 12.4 times that of P1/SWCNTs at the same SWCNT mass ratio.More-over,CPEs/SWCNTs composites (P2/SWCNTs) display remarkably improved thermoelectric properties with the highest power factor (PF) of 163 μW·m-1 ·K-2.In addition,a thermoelectric generator is fabricated with P2/SWCNTs com-posite films,and the output power and power density of this generator reach 1.37 μW and 1.4 W·m-2 (cross-section) at△T 70 K.This result is over three times that of the thermoelectric generator composed of non-CPEs/SWCNTs com-posite films (P1/SWCNTs,0.37 μW).The remarkably improved electrical conductivities and thermoelectric properties of the CPEs/SWCNTs composites (P2/SWCNTs) are attributed to the enhanced interaction.This method for constructing CPEs/SWCNTs composites can be applied to produce thermoelectric materials and devices.
