ned highly porous CNT foam with porosity exceeding 90% exhibits a low thermal conductivity of 0.17 W m−1 K−1 with increased phonon scattering, which is 100 times lower than that of a CNT film with a densely packed network. Finally, optimized p- and n-doped CNT foams are used to fabricate a vertical and flexible TE power generator with a combination of series and parallel mixed circuits. The maximum output power and output power per weight of the TE generator reach 1.5 μW and 82 μW g−1, respectively, at a temperature difference of 13.9 K. |
