根据以往的研究,硬脂酸因其优良的相变蓄热性能,而受到越来越多的关注。然而,硬脂酸导热性能较差,易发生液相泄露且相变温度单一,限制了其在较多领域的应用。通过分析现有文献,综述了导致硬脂酸热导率低和液相泄漏等问题的原因及解决方法,并指出各方法中的不足之处,总结了硬脂酸复合相变材料的优点,并对硬脂酸复合相变材料的未来发展做出了展望。
According to previous studies,stearic acid has attracted more and more attention due to its excellent phase change heat storage performance.However,the poor thermal conductivity,leakage and single phase transition temperature of stearic acid limit its application in many fields.By analyzing the existing literatures,the causes and solutions for the problems of stearic acid,such as low thermal conductivity and liquid leakage,were reviewed,and pointed out the shortcomings of each method.The advantages of the materials were summarized,and prospected the future development of such materials.
