微胶囊化相变材料的制备与评价方法

微胶囊化相变材料(MCPCM)是将微胶囊技术应用于相变材料而形成的新型复合材料,具有广阔的应用前景,现已成为相变材料应用研究领域的热点。该文综述了MCPCM的4种主要制备方法——原位聚合法、界面聚合法、凝聚法和喷雾干燥法的原理及国内外研究情况。总结了MCPCM的评价方法,将文献中常见的评价指标分成了两类,即"与制备有关的评价指标"和"与应用有关的评价指标",并介绍了相应的表征手段。指出了MCPCM在选材、制备及评价等方面存在的问题和今后的研究方向。

Preparation and Evaluation Methods of Microencapsulated Phase Change Materials

Microencapsulated phase change materials(MCPCM),a new kind of composite functional materials with widespread applications,can be prepared by micro-encapsulation technology.Main preparation methods of MCPCM,i.e.in situ polymerization,interfacial polymerization,single & complex coacervation and spray drying,were reviewed,including their principles and state-of-the-art at home and overseas.Evaluation methods and characterization techniques of MCPCM products were generalized and classified as two groups,i.e.preparation-relevant evaluating indicators and application-relevant ones.Open questions in the materials selection,preparation and evaluation methods of MCPCM and researches in the future were pointed out.
