摘要

微量硼酸盐与Ti3C2Tx羟基之间的强共价交联显著减小了层间间距，增强了取向性和致密性，从而显著提高了Ti3C2Tx纤维的力学性能（抗拉强度为188.72 MPa）和电性能（7781 S cm−1）。微量硼酸盐可以促进Ti3C2Tx纤维界面结构的规正化，降低界面热阻，显著提高Ti3C2Tx纤维的导热系数（13 W m−1 K−1），从而增加其高效传热应用的潜力。

Thermally Conductive Ti3C2Tx Fibers with Superior Electrical Conductivity

Highlights

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.

期刊介绍： Nano-Micro Letters is a peer-reviewed, international, interdisciplinary, and open-access journal published under the SpringerOpen brand. Nano-Micro Letters focuses on the science, experiments, engineering, technologies, and applications of nano- or microscale structures and systems in various fields such as physics, chemistry, biology, material science, and pharmacy.It also explores the expanding interfaces between these fields. Nano-Micro Letters particularly emphasizes the bottom-up approach in the length scale from nano to micro. This approach is crucial for achieving industrial applications in nanotechnology, as it involves the assembly, modification, and control of nanostructures on a microscale.
