在这项工作中，研究了支撑材料类型对形状稳定相变材料（FSPCM）性能的影响。分别使用无机材料（膨润土）和聚合物（Eudragit L100）作为支撑材料制备了两种含有肉豆蔻酸（MA）的FSPCM。对IVIA/膨润土FSPCM（简称FSPCM-B）和MA/Eudragit L100 FSPCM（简称FSPCM-E）的形貌、组成、结晶性能、相变性能和储放热性能进行了对比研究。结果表明，没有熔体MA泄漏的FSPCM-B和FSPCM-E的最大MA含量分别为50wt%和70wt%。所制备的FSPCM均具有良好的热可靠性和可重复使用性，并且相同MA质量分数的FSPCM-B的相变焓明显低于FSPCM-E。由于膨润土的高导热率，FSPCM-B的传热速率恰好高于FSPCM-E。这项研究将为无机基体和聚合物基体的 FSPCM 的设计和应用提供见解。 (C) 2014 Elsevier B.V. 保留所有权利。
In this work, the influence of type of supporting materials on the performance of form stable phase change materials (FSPCMs) was investigated. Two kinds of FSPCMs containing myristic acid (MA) were prepared using an inorganic material (bentonite) and a polymer (Eudragit L100) individually as the supporting material. The morphology, composition, crystalline properties, phase transition properties and heat storage/release performances of IVIA/bentonite FSPCMs (abbreviated as FSPCM-B) and MA/Eudragit L100 FSPCMs (abbreviated as FSPCM-E) were researched comparatively. The results show that the maximum MA content of FSPCM-B and FSPCM-E without melt MA leakage is 50 wt% and 70 wt%, respectively. All the prepared FSPCMs have good thermal reliability and reusability, and phase transition enthalpies of FSPCM-B are obviously lower than those of FSPCM-E with the same MA mass fraction. Due to the high thermal conductivity of bentonite, the heat transfer rate of FSPCM-B is exactly higher than that of FSPCM-E. This study will provide insights into the design and application of FSPCMs with inorganic matrix and polymeric matrix. (C) 2014 Elsevier B.V. All rights reserved.
