Flexible titanium carbide–carbon nanofibers with high modulus and high conductivity by electrospinning

• Titanium carbide–carbon nanofibers were successfully prepared by electrospinning.
• High modulus (446 GPa) of single titanium carbide–carbon nanofiber.
• High conductivity (25 S/cm) of titanium carbide–carbon nanofiber felt.
• High flexibility with 200 bending cycles.
• Conductivity remains 96% and 92% after 60 and 100 bending cycles, respectively.

Titanium carbides are well-known for their outstanding mechanical and thermal stabilities. However, the studies on the mechanical properties and the conductivity of titanium carbide–carbon nanofibers (TiC/CNF) are missing. This work prepared TiC/CNF by electrospinning and highlighted the high modulus of single TiC/CNF, the flexibility and the excellent electrical conductivity of TiC/CNF felt even under 100 bending cycles. This flexible TiC/CNF felt with distinguished mechanical and electrical properties are promising to apply in titanium matrix composites (TMC), efficient catalyst scaffolds and electronic devices.
