Abstract

We prepare binary phase change materials by using decanoic acid-lauric acid and use swelling vitrified beads as adsorption carrier, adoptting vacuum adsorption method to prepare composite phase change material. We measure that the phase change temperature and phase change latent heat of different proportions of decanoic acid and lauric acid and that phase change temperature and phase change latent heat of composite phase change materials after adsorption by using DSC. Using scanning electron microscopy (SEM) to characterize the microstructure of composite materials. The results show that: when CA:LA=7:3,phase change latent heat is highest, it reaches 143.48J/g, the phase transition temperature is 23.93 , endothermic peak area is 659.57mJ; In composite phase change materials, suitable proportion of phase change materials and the carrier is 1.8:1, at this time , the phase transition temperature is 21.73 , phase change latent heat of 120.04 J/g , endothermic peak area is 495.02 mJ.
