Abstract

Abstract:

Carbon based materials have a wide absorption range for sunlight，high photothermal conversion efficiency，and excellent thermal conductivity and can be used for photothermal conversion of solar power. They are key materials for achieving green utilization of renewable solar energy. However，solar radiation is intermittent，which is unfavorable for the large-scale utilization of solar energy. Therefore，by combining carbon based photothermal materials with phase change materials，the solar energy absorbed by the photothermal materials can be stored in the phase change materials for nighttime use. This research summarized and classified carbon based photothermal conversion materials，reviewed the composite encapsulation strategies of carbon based photothermal conversionand phase change materials，summarized the effects of different combination methods on photothermal conversion efficiency and thermal storage performance，and briefly introduced the applications of photothermal phase change composites in solar water heaters，building energy conservation，and human-body thermal management. Finally，the future development direction of carbon based photothermal phase change composites wasanalyzed，providing references for the preparation of new photothermal phase change composites with high conversion efficiency.

Key words: photothermal material, carbon based material, phase change energy storage, thermal management, encapsulation strategy

摘要：

碳基材料具有宽的太阳光吸收范围、高的光热转化效率及优异的导热性能，可用于太阳能光热转化，是实现绿色可再生太阳能利用的关键材料。然而太阳辐射存在间断性，不利于太阳能的规模化利用。因此，将碳基光热材料与相变材料复合使用，可以将光热材料吸收的太阳能储存在相变材料中以供夜间使用。本文对碳基光热转化材料进行分类总结，综述碳基光热转化材料与相变材料复合封装策略，总结不同复合方法对光热转换效率及储热性能的影响，并简单介绍光热复合相变材料在太阳能热水器、建筑节能、人体热管理领域的应用。最后，展望了碳基光热复合相变材料的未来发展方向，为制备高转化效率的新型光热相变复合材料提供参考。
