本研究首次报道了以食品级椰子油和椰壳活性炭为前驱体合成生物基形状稳定相变材料（bioSSPCM）。尽管熔融焓低，但通过加热和混合的简单物理共混是一种非常可靠的制备方法，可以生产出热稳定且防泄漏的生物osspcm。食用级和分析级椰子油在sspcm中的应用没有明显差异。进一步比较了椰子油与常规相变材料十八烷的性能，发现在相同的合成条件下，椰子油的稳定性得到了提高，相变循环后的泄漏量更少。
This research reports, for the first time, the combination of food-grade coconut oil and coconut shell-based activated carbon as precursors for the synthesis of bio-based shape-stabilized phase change materials (bioSSPCM). Despite its low melting enthalpy, simple physical blending by heating and mixing is found to be a very reliable preparation method for the completely coconut-based materials, producing a thermally stable bioSSPCM with anti-leakage. No difference between food grade and analytical grade coconut oil, in terms of its application for SSPCMs, was evident. Further, comparing the performance of coconut oil against octadecane, a conventional phase change material, it was found that with the same synthesis conditions, the coconut oil exhibited improved stability, with less leakage after phase change cycling.
