Fig. 4: The comparison of TE and mechanical performances.

A comparison of power factors, tensile modulus, fracture strength of PC/a-SWCNT composite in the aligned direction (SWCNT: 10 wt%), PPy/SWCNT composite (SWCNT: 10 wt%)18 and 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) doped P3HT material55. Note that the fracture strength of the doped P3HT material was not given in ref. 55. and its true value is even lower than the value here that is estimated by neat P3HT material. Error bars in PC/a-SWCNT composite represent standard deviation with n ≥ 5 for each measurement, and error bars in PPy/SWCNT and P3HT materials are from the values in refs. 18,55.
