Single-walled carbon nanotubes (SWCNTs) are promising candidates for use in thermoelectric generators (TEGs) to power Internet of Things (IoT) sensors. For practical applications, the major challenge SWCNTs is improving performance and thermal durability n-type SWCNT films. Here, inks were prepared using a dopant, which cationic surfactant dimethyldioctadecylammonium chloride (DODMAC), by changing mass ratio DODMAC/SWCNT. The films fabricated vacuum filtering, followed heat treatment at 423 K. in-plane properties measured 300 K, Seebeck coefficient changed from positive negative values when DODMAC/SWCNT was 10−2. highest dimensionless figure-of-merit, ZT, 1.0 × 10−2 exhibited 80, close saturation concentration. This ZT achieved mainly because conductivity decreased significantly 0.16 W/(m · K), it currently one among those with various dopants. To demonstrate generation, we SWCNT-TEG consisting ZT. an output voltage 24 mV maximum 0.9 μW temperature difference 80 Furthermore, investigate films, cycling tests performed temperatures ranging film durability. These findings will contribute widespread SWCNT-TEGs as sources IoT
