Research progress in fatty acids as phase change materials and their application

Middle/Long chained fatty acids and their mixtures have superior properties such as good thermophysical property,thermal and chemical stability,they are a kind of cheap and easily obtainable organic phase change materials (PCMs).In this paper,the development status of fatty acids,their thermo-physical properties and thermal stability and their eutectic mixtures as PCMs for latent heat thermal storage (LHTS) are reviewed.The heat transfer enhancement of fatty acids and the preparation methods of composite ph...
