| Abstract Scope |
The increasing demand for efficient heat dissipation in modern technologies calls for materials that are not only excellent thermal conductors but also cost-effective, lightweight, easy to manufacture, and corrosion-resistant. Polymers are often chosen for their versatility, meeting most of these criteria, but their inherently low thermal conductivity limits their use in advanced thermal management systems. This challenge has sparked extensive research to enhance the thermal conductivity of polymers. My research focuses on improving the thermal conductivity of polymers through internal structure engineering. In this talk, I will present our recent work on the preparation of single polyethylene oxide (PEO) nanofibers, the measurement of their thermal conductivity, and the characterization of their internal structures, including crystallinity and molecular orientation. Subsequently, I will explore the relationship between thermal properties and structure. |
