Noncovalent interactions play a critical, but not yet understood, role in enhancing the thermoelectric properties of carbon nanotube composites. We herein report the dispersion of synthetic MoS 2 flakes and their self‐assembly with single‐walled carbon nanotubes via in‐plane and multipoint S–π interactions. The hybridization of MoS 2 and carbon nanotubes leads to improved electrical and thermoelectric transport, and resulted in a tenfold enhancement of the thermoelectric figure‐of‐merit of nanotube‐based films. The present technique could contribute to advancing the flexible energy materials that harvest abundant waste heat.
