| 摘 要： | 赤藓糖醇具有较高的相变焓、无毒以及优异的热稳定性，作为综合性能较好的中温相变储能材料被广泛研究。但是，赤藓糖醇在相变过程中存在易泄漏、过冷度大以及导热性能较差的缺点，导致其热能的利用效率不高，极大地限制了其作为储热材料的应用。本文综述了近年来在解决赤藓糖醇相变储热材料易泄漏、过冷度高和热导率低等问题的研究进展。赤藓糖醇定型复合相变储热材料的制备方法主要有共混压制法、静电纺丝法、微胶囊法及多孔材料吸附法等，可根据不同制备方法采取相应复合策略以达到对其封装定型、降低过冷度和提高热导率的目的。最后认为未来对赤藓糖醇复合相变储热材料的研究除了解决其本身存在的热性能问题，还需对其进行功能化，以拓展其应用前景。

| Abstract: | Erythritol, a type of medium temperature phase change material, has attracted considerable attention in thermal storage for its good comprehensive performance such as high enthalpy, non-toxicity and excellent thermal stability. However, its ubiquitous defects, such as easy leakage during its phase transition, severe supercooling and poor thermal conductivity, reduce the efficiency of thermal energy and limit its wide practical application. In this paper, the research progress in solving the problems of easy leakage, high supercooling and low thermal conductivity of erythritol phase change materials is reviewed in recent years. The methods for preparing shape-stabilized erythritol phase-change thermal storage materials mainly include blending pressing, electrospinning, microcapsule and porous material adsorption. Corresponding composite strategies can be implemented according to different preparation methods to achieve the purpose of package, supercooling reducing and enhancement of thermal conductivity. It is believed that the future research toward erythritol phase-change thermal storage materials not only focuse on thermal properties, but also considere multi-functionalization of erythritol phase-change materials for widening its applications. |
