生物质碳基复合相变材料在热能存储中的性能调控与应用

Abstract With the continuous growth of global energy consumption, significant attention is being directed toward the development of efficient energy storage materials . Phase change materials (PCMs) are known for their excellent thermal energy reservoir characteristics and their capability to keep relatively stable temperature during the phase transition process. It has received great attention in the realm of thermal energy storage. This is due to their excellent thermal storage capabilities and superior heat regulation. However, difficulties such as material leakage and poor thermal conductivity limit their application potential in diverse environments. In order to optimize the thermal properties of PCMs, biomass based porous media, which are cost-effective, sustainable, and commonly used, can be used as the support material to effectively prepare shape-stable biomass composite phase change materials. This paper reviews the synthesis and research progress of biomass carbon based CPCMs, discusses their impact on the thermal properties of the underlying PCMs and the challenges encountered in the realm of solar energy harvesting, electronics, thermal management in buildings and waste heat recovery, and supplies a reference for further research on biomass carbon based CPCMs.
