Thermal smart materials with tunable thermal conductivity: Mechanisms, materials, and applications

The demand for active and effective management of heat transfer is increasing in various modern application scenarios. thermal conductivity materials plays a key role systems, reversibly tunable properties are one the fundamental needs materials. Thermal smart materials, whose can be tuned with an external trigger, have attracted attention researchers. In this paper, we provide brief review current research advances recent years terms physical mechanisms, switching ratios, their value. We focus on typical such as nanoparticle suspensions, phase change polymers, layered by electrochemistry other specific field. After surveying present applications components devices temperature control, circuits, phonon computers, metamaterials, so on. Finally, discuss limitations challenges well our predictions future development.
