从无机载体的改性和复合方法两方面介绍了如何提高石蜡基相变储能材料的热稳定性。综述了硅藻土、膨胀石墨、高岭土等无机材料的改性方法,总结了复合材料的制备方法,分析了插层复合法、吸附法等方法的优缺点。最后提出了无机载体材料改性及复合方法是石蜡基复合材料的研究方向和未来研究的重点。 How to improve the thermal stability of paraffin-based phase change energy storage materials is introduced from the aspects of modification and compounding of inorganic carriers. The modification methods of inorganic materials such as diatomite, expanded graphite and kaolin are reviewed. The preparation methods of composite materials are summarized. The advantages and disadvantages of the methods such as intercalation compound method and adsorption method are analyzed. At last, it is put forward that the modification and compounding method of inorganic carrier materials are the research direction and future research focus of paraffin-based composites.
