Thermally Conductive Ti3C2Tx Fibers with Superior Electrical Conductivity

Abstract High-performance Ti 3 C 2 T x fibers have garnered significant potential for smart fibers enabled fabrics. Nonetheless, a major challenge hindering their widespread use is the lack of strong interlayer interactions between Ti 3 C 2 T x nanosheets within fibers, which restricts their properties. Herein, a versatile strategy is proposed to construct wet-spun Ti 3 C 2 T x fibers, in which trace amounts of borate form strong interlayer crosslinking between Ti 3 C 2 T x nanosheets to significantly enhance interactions as supported by density functional theory calculations, thereby reducing interlayer spacing, diminishing microscopic voids and promoting orientation of the nanosheets. The resultant Ti 3 C 2…
