Thermal energy harvesting technologies based on composite phase change materials (PCMs) are capable of harvesting tremendous amounts of thermal energy via isothermal phase transitions, thus showing enormous potential in the design of state-of-the-art renewable energy infrastructure. Great progress has been recently made in terms of enhancing the thermal energy storage capability, transfer rate, conversion efficiency and utilization of composite PCMs. Although there are some recent reviews on composite PCMs, they are mainly concentrated on the thermal transfer enhancement and conventional utilization of PCMs. There are few systematic reviews concerning optimization strategies of PCM for thermal energy conversion. In particular, advanced multifunctional utilization of PCMs is still in its infancy. Herein, we systematically summarize the optimization strategies and mechanisms of recently reported composite PCMs for thermal energy storage, thermal transfer, energy conversion (solar-to-thermal, electro-to-thermal and magnetic-to-thermal conversion) and advanced utilization (fluorescence emission, infrared stealth technologies, drug release systems, thermotherapy and thermal protection), including some novel supporting materials (BN nanosheets and metal organic frameworks (MOFs)). Simultaneously, we provide in-depth and constructive insights into the correlations between the structural optimization strategies and thermal performances of composite PCMs. Finally, future research trends, alternative strategies and prospects are also highlighted according to up-to-date optimization strategies.

复合相变材料热能存储，传递，转化和利用的优化策略

基于复合相变材料（PCMS）热能收集技术能够收获热巨大的能量的经由等温相变，因此在设计最新的可再生能源基础设施中显示出巨大的潜力。最近在增强热能存储能力，传递速率，转换效率和复合PCM利用率方面取得了巨大进展。尽管最近有一些关于复合PCM的评论，但它们主要集中在增强热传递和PCM的常规利用上。关于热能转换PCM优化策略的系统评价很少。特别是，PCM的高级多功能利用仍处于起步阶段。在此，我们系统地总结了最近报道的复合PCM在热能存储，热传递，能量转换（从太阳能到热能，电热和磁热转换）和先进的利用（荧光发射，红外隐身技术，药物释放系统，热疗和热保护），包括一些新型的支撑材料（BN纳米片和金属有机骨架（MOF））。同时，我们对复合材料PCM的结构优化策略与热性能之间的相关性提供了深入而建设性的见解。最后，还将根据最新的优化策略突出未来的研究趋势，替代策略和前景。包括一些新颖的支撑材料（BN纳米片和金属有机骨架（MOF））。同时，我们对复合材料PCM的结构优化策略与热性能之间的相关性提供了深入而建设性的见解。最后，还将根据最新的优化策略突出未来的研究趋势，替代策略和前景。包括一些新颖的支撑材料（BN纳米片和金属有机骨架（MOF））。同时，我们对复合材料PCM的结构优化策略与热性能之间的相关性提供了深入而建设性的见解。最后，还将根据最新的优化策略突出未来的研究趋势，替代策略和前景。
