摘　　要：作为潜热储能(LHS)储热介质的相变材料(PCMs),因其具有较高的储能密度,能在较窄的温度区间内实现能量的存储与释放等优势而备受研究者的关注。然而,相变材料因自身较低的热导率及其相变储热过程所伴随的体积变化,使相变材料应用受到一定限制。对相变材料进行微胶囊化封装,可显著增加其传热面积与吸收其在相变过程的体积变化。综述了相变材料微胶囊化封装的合成方法,总结了研究工作中亟待解决的问题和技术难点,为今后相变材料的研究提供一定的理论支持。Latent heat storage(LHS)using phase change materials(PCMs)as the heat storage medium has attracted worldwide researchers’attention due to high energy storage density and the ability of storing or releasing energy in a narrow temperature range.However,the thermal conductivity and volume change accompanying the phase change heat storage process have led to certain restrictions on applications.The microencapsulation on phase change materials can significantly increase the heat transfer area and absorb the volume change during the phase change process.Based on this,we systematically review the synthesis methods of microencapsulated phase change materials,and summarize the scientific problems and technical difficulties that need to be solved urgently.This article also provides certain theoretical support for the future research on phase change materials.
