癸酸-月桂酸相变微胶囊的制备及性能研究
Preparation and Properties of Capric Acid-lauric Acid Phase Change Microcapsules
摘要
Abstract
The aim of this study is to develop an efficient heat storage and temperature regulating material suitable for a variety of thermal energy storage systems.The capric acid-lauric acid(CA-LA)low eutectic mixture was encapsulated in a poly(ethyl acrylate)(PEA)shell through emulsion polymerization to form PEA/(CA-LA)phase change material microcapsule(MEPCM).Analysis results demonstrate that the prepared MEPCM exhibits a uniform and smooth spherical appearance,with no chemical reaction occurring between the core and shell materials.At a shell-core ratio of 1∶1.5,the latent heat of melting and solidification are 81.85 J/g and 88.68 J/g,respectively.The latent heat storage capacity of MEPCM increases with an increase in core material ratio.Through thermogravimetric analysis and leakage testing,it is observed that MEPCM maintains excellent latent heat storage and release ability below 160℃.Even after 200 thermal cycles,it still demonstrates good thermal stability and practical application value.关键词
