Abstract

A kind of latent heat storage microcapsule was prepared using lauric acid as core and melamine-formaldehyde resin as shell via in-situ polymerization.The core-to-shell mass ratio was 1∶1.The chemical composition,thermal properties and surface morphology of the obtained microcapsules were characterized by FTIR,DSC and SEM,respectively.The results show that the obtained microcapsules have spherical appearance and porous network structures.The melting point and fusion enthalpy of the microcapsules are 43.7 ℃ and 84.96 J/g,respectively,which mean the microcapsules possess a good potential as a latent heat storage material in latent heat thermal storage applications.

脂肪酸微胶囊化相变材料的潜热储存研究

以月桂酸为芯材，三聚氰胺甲醛树脂为壳材，采用原位聚合法制备了一种潜热储微胶囊。核壳质量比为1∶1。用FTIR、DSC和SEM分别表征了微胶囊的化学成分、热性能和表面形貌。结果表明，制备的微胶囊具有球形和多孔网络结构。微胶囊的熔点和熔合焓分别为43.7℃和84.96 J/g，表明微胶囊作为潜热储热材料在潜热储热应用中具有良好的潜力。
