中文摘要 有机相变材料(PCM)在相变过程中发生泄漏，大大地限制了它们的实际应用。为解决这一问题，本文以藤材为骨架，石蜡为相变材料，通过多孔材料物理吸附凝结法将石蜡浸入藤材中，成功制备出藤材基相变储能材料。通过场发射扫描电镜(FE-SEM)观察藤材和藤材基相变储能材料的微观形貌，通过傅里叶变换红外(FTIR)光谱、X射线衍射(XRD)和热重(TGA)分别分析藤材、石蜡和藤材基相变储能材料的官能团、结晶特性和热解性能，用差示扫描量热仪(DSC)分析石蜡和藤材基相变储能材料的热力学性能。结果表明，藤材基相变储能材料的吸收峰和衍射峰是藤材和石蜡的叠加，说明二者仅为物理吸附；所制备的藤材基相变储能材料中石蜡与藤材能很好的相互结合，基本无泄漏，相变温度为52.56 ℃，相变焓值为96.96 J/g，藤材基相变储能材料中石蜡含量为52.3%。由此可见，藤材是一种理想的多功能PCM骨架，可以促进PCM复合材料的实际应用。

英文摘要 The leakage of organic phase change materials (PCM) during phase transition greatly limits their practical application. In order to solve this problem, this paper uses rattan as the skeleton and paraffin wax as the phase change material to successfully prepare the rattan-based phase change materials for energy storage by immersing paraffin wax into rattan with porous materials having the ability of physical adsorption condensation. Field emission scanning electron microscopy (FE-SEM) is used to observe the morphology of rattan and rattan-based phase change energy storage materials. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and thermograying (TGA) are employed to analyze the functional groups, crystallization properties and pyrolysis properties of rattan, paraffin wax and rattan-based phase change energy storage materials, respectively. The thermodynamic properties of paraffin and rattan-based phase change energy storage materials are analyzed using differential scanning calorimeter (DSC). It is found that the absorption peak and the diffraction peak of rattan-based phase change energy storage material are superimposed by rattan and paraffin wax, indicating that they are only physical adsorption. The paraffin wax and rattan in the prepared rattan-based phase change energy storage material can combine well with each other, basically allowing no leakage, with phase change temperature at 52.56℃, phase change enthalpy value at 96.96 J/g, and paraffin content in rattan-based phase change energy storage material at 52.3%. Therefore, rattan is an ideal multifunctional PCM scaffold, which can promote the practical application of PCM composite materials.
