A novel shape‐stabilized n‐hexadecane/polyHIPE composite phase change material (PCM) was designed and thermal energy storage properties were determined. Porous carbon‐based frameworks were produced by polymerization of styrene‐based high internal phase emulsions (HIPEs) in existence of the surface modified montmorillonite nanoclay. The morphological and mechanical properties of the obtained polyHIPEs were investigated by scanning electron microscopy analysis and the compression test, respectively. The polyHIPE composite with the best pore morphology and the highest compression modulus was determined as a framework to prepare the form stable n‐hexadecane/polyHIPE composite phase change material using the one‐step impregnation method. The chemical structure and morphologic property of composite PCM was investigated by FT‐IR and polarized optical microscopy analysis. Thermal stability of the form‐stable PCM (FSPCM) was examined by TG analysis. The n‐hexadecane fraction engaged into the carbon foam skeleton was found of as 55 wt% from TG curve. differential scanning calorimetry analysis was used for determining melting temperature and latent heat storage capacity of FSPCM and these values were determined as (26.36°C) and (143.41 J/g), respectively. The results indicated that the obtained composite material (FSPCM) has a considerable potential for low temperature (18°C‐30°C) thermal energy storage applications with its thermal energy storage capacity, appropriate phase change temperatures and high thermal stability.

用于储热的PolyHIPE复合材料基稳定相变材料
设计了一种新型的形状稳定的正十六烷/ polyHIPE复合相变材料（PCM），并确定了热能存储特性。在存在表面改性的蒙脱土纳米粘土的情况下，通过苯乙烯基高内相乳液（HIPE）的聚合反应制得了多孔碳基骨架。分别通过扫描电子显微镜分析和压缩试验研究了所得的聚HIPE的形态和力学性能。确定具有最佳孔隙形态和最高压缩模量的polyHIPE复合材料为骨架，以制备稳定的n一步浸渍法制备十六烷/ polyHIPE复合相变材料。通过FT-IR和偏振光学显微镜分析研究了复合PCM的化学结构和形态学特性。通过TG分析检查了形状稳定的PCM（FSPCM）的热稳定性。该ñ从TG曲线发现，参与碳泡沫骨架的十六烷部分为55 wt％。差示扫描量热法分析用于确定FSPCM的熔融温度和潜热储存能力，并且这些值分别确定为（26.36℃）和（143.41J / g）。结果表明，所获得的复合材料（FSPCM）具有储热能力，合适的相变温度和高热稳定性，在低温（18°C–30°C）储热应用中具有巨大潜力。
