Abstract: • Both core–shell RC@GM and GM@RC fibers are fabricated by coaxial wet spinning. • Coaxial spinning endows fibers with enhanced mechanical and electrical properties. • The hollow RC@GM fiber with the RC shell exhibits a high toughness of 14.1 MJ m−3. • The fibers show high EMI shielding, solar-thermal and electro-thermal performances. Although transition metal carbide (MXene) fibers are highly electrically conductive, the poor spinnability of neat MXene dispersion and the brittleness of the conductive fibers limit their applications. Herein, a coaxial wet spinning assembly strategy is adopted to fabricate mechanically strong and electrically conductive Ti 3 C 2 T x MXene-based core–shell fibers with regenerated cellulose (RC) as the tough component and graphene oxide/MXene (GM) as the conductive components. By an optimal structure design, the hollow RC@GM 90 fiber with the RC shell exhibits an increased strength of 134.7 MPa, a high toughness of 14.1 MJ m−3, a large elongation at break of 13%, and a high conductivity of 2.37×103 S m−1. By sewing on a textile substrate, the hollow RC@MXene fibers with a high conductivity of 3.68×104 S m−1 provide an extraordinary electromagnetic interference shielding efficiency of over 90 dB and outstanding solar-thermal energy conversion performances. Similarly, by improving spinnability of the MXene spinning dope with an aqueous dispersion of GO, solid core–shell GM@RC fibers with conductive GM shells are fabricated by the coaxial spinning, and the chemically reduced GM@RC fibers exhibit a high conductivity of 9.90×104 S m−1 and excellent electro-thermal energy conversion performances.
