Lotus-root-fiber inspired stretchable and self-healing ionic thermoelectric gels with carbon nanotubes for enhanced high-temperature performance

MWCNTs are incorporated into the i-TE gel G-FeCN 4−/3− to simultaneously enhance stretchability, self-healing capacity, and i-TE performance with a P max /(Δ T ) 2 of 1.7 mW m −2 K −2 and S i of 11 mV K − 1 at 313 K.
