Abstract

The strong covalent crosslinking between trace amounts of borates and the hydroxyl groups of Ti₃C₂T_x significantly reduces interlayer spacing, enhances orientation and compactness, leading to notable improvements in both the mechanical (tensile strength of 188.72 MPa) and electrical properties (7781 S cm⁻¹) of Ti₃C₂T_x fibers. Trace amounts of borates can promote the regularization of interfacial structures, reduce interfacial thermal resistance, and significantly enhance the thermal conductivity (13 W m⁻¹ K⁻¹) of Ti₃C₂T_x fibers, thus increasing their potential for efficient heat transfer applications.
