摘　　要：相变储能复合材料对于缓解能源紧张状况,保护环境和提供舒适健康的生活环境具有积极的意义,在太阳能热发电、工业热利用及余热回收方面有显著优势。但是相变材料本身存在导热性能不高,容易腐蚀容器等问题,所以本文主要综述了相变材料导热性能强化的研究进展。首先介绍相变储能材料的现状以及存在的问题,然后讨论了以金属、陶瓷和碳质纳米材料作为导热强化材料在相变储能复合材料中的研究现状和成果,最后展望了经导热强化后的相变储能复合材料的前景。Phase change composites for thermal energy storage offered a useful technology for relieving energy shortage,protecting environment and providing healthy living environment,and had obvious advantages in solar thermal power generation,industrial process heat use and waste heat recovery and so on.But phase change materials themselves had some defects such as low thermal conductivity and easy to corrode the container,so progress in phase change materials with enhanced thermal conductivity was reviewed.At first,current development status of phase change materials for energy storage was introduced,then research results of the composites with enhanced thermal conductivity by adding metal,ceramics and carbonaceous nanomaterials were discussed.At last,some prospective developments of the composites with enhanced thermal conductivity were anticipated.
