Engineering Two-Dimensional Material Derived Fiber System for Directional Thermal Regulation

Thermal management is critical for electronics, energy, and wearable systems, especially as devices shrink and power density rises. Traditional methods fall short, prompting interest in 2D material-based fibers for their high thermal conductivity, anisotropy, and tunability. This thesis establishes such fibers as a platform for next-gen thermal control by enhancing conductivity, enabling directional conduction and convection, and coupling heat with mass transport. It targets five key objectives spanning anisotropic design to hollow-fiber channels and modeling frameworks. Bridging microscale design with macroscale function, the work offers a unified strategy for programmable, multifunctional heat control in flexible electronics and smart textiles.<p></p>
