| 摘 要： | 在以往所研究的相变材料中，脂肪酸由于展现出优越的性能，得到了研究者更多的关注，但同样存在相变温度不适宜和导热性能差等热性能问题。本工作通过现有文献对脂肪酸相变储能材料的热性能进行系统分析，提出了脂肪酸与脂肪酸、脂肪醇及石蜡复合3种有效解决相变温度不适宜的方法；针对导热性能差提出了多孔材料吸附、添加碳材料或金属粒子和微胶囊化3种高效易行的强化传热方式，进而说明这一领域目前研究重点。同时，对脂肪酸储能材料的相变性能、导热增强方法及导热增强剂进行了比较，分析了各自的优缺点。最后，对脂肪酸相变储能材料热性能研究的不足之处进行了探究，并指出了制备出更多能应用于建筑节能和纺织等领域的脂肪酸相变储能材料和着重研究脂肪酸与石蜡的复合等进一步研究方向。

| Abstract: | Fatty acids have attracted more attention from researchers due to their superior performancein the phase change materials studied formerly, but there are also some problems such as inappropriate phase change temperature and poor thermal conductivity. Thermal properties of fatty acid phase change energy storage materials (PCMs) were systematically analyzed through the existing literature, three effective methods to solve the problem of inappropriate phase change temperature were presented, which are combination of fatty acid with fatty acid, fatty alcohol and paraffin. In view of the poor thermal conductivity, three efficient and easy ways to enhance heat transfer, namely, porous material adsorption, adding carbon materials or metal particles and microencapsulation, are proposed and illustrated the current research focus in this area. Meanwhile, the phase change properties, thermal conductivity enhancement methods and thermal conductivity enhancers were compared, and their advantages and disadvantages were analyzed. Finally, the shortcomings of the study on thermal properties were investigated and further research directions are pointed out, such as preparing more fatty acid PCMs which can be used in building energy saving and textile industry, and emphasizing on the study of the composition of fatty acid and paraffin. |
