“…In 2016, the same research group reported a further increased power factor of 217 W/m-K 2 for SWCNT-PANI composites produced from the similar process [214]. In both studies [208,214], the substantially enhanced power factor compared to earlier studies [182,212,213] is primarily caused by the orders of magnitude improvement in , which is enabled by the much better structural regularity.…”

“…In 2014, Yao et al synthesized SWCNT-PANI composites with an even higher power factor of 176 W/m-K 2 [208], by dissolving camphor sulfonic acid (CSA)-doped PANI in m-cresol solvent to expand the PANI coil. As shown in Figure 14, the expanded PANI had larger area to interact with SWCNTs, leading to more ordered composite structure.…”

This article reviews the recent progress towards achieving carbon-based thermoelectric materials. A wide range of experimental and computational studies on carbon allotropes and composites is covered in this review paper. Specifically, we discuss the strategies for engineering graphene, graphene nanoribbon, graphene nanomesh, graphene nanowiggle, carbon nanotube (CNT), fullerene, graphyne, and carbon quantum dot for better thermoelectric performance. Moreover, we discuss the most recent advances in CNT/graphene-polymer composites and the related challenges and solutions. We also highlight the important charge and heat transfer mechanisms in carbon-based materials and state-of-the-art strategies for enhancing thermoelectric performance. Finally, we provide an outlook towards the future of carbon-based thermoelectrics.

A new compound of Cu 5 AlSn 2 S 8 , which contained earth-abundant and environment-friendly elements and had a diamond-like crystal structure, was designed, and its electronic structure and thermoelectric transport properties from 300 K to 700 K were investigated by first-principles calculations, Boltzmann transport equations, and a modified Slack's model. The largest power factors of Cu 5 AlSn 2 S 8 at 700 K were 47.5 9 10 10 W m À1 K À2 s À1 and 14.7 9 10 10 W m À1 K À2 s À1 for p-and n-type semiconductors, respectively. The lattice thermal conductivity of Cu 5 AlSn 2 S 8 was calculated with its shear modulus and isothermal bulk modulus, which were also obtained by first-principles calculations. The lattice thermal conductivity was 0.9-2.2 W m À1 K À1 from 300 K to 700 K, relatively low among thermoelectric compounds. This theoretical study showed that Cu 5 AlSn 2 S 8 could be a potential thermoelectric material.
