Preparation of Epoxy/PEG Shape-Stabilized Phase Change Materials by In Situ Reactive Blending

Abstract:

Recently, solid-liquid phase change materials (PCMs) have caused much attention due to their large latent heat. In order to solve their sealed problem, shape-stabilized methods have become a popular research topic. In this study, we prepared epoxy/polyethylene glycol (PEG) shape-stabilized PCMs with different mass ratios successfully by in-situ reactive blending. The maximum mass percentage of PEG dispersed into epoxy to form epoxy/PEG shape-stabilized PCM was determined as 70wt % by observing the morphology at the temperature above the phase transition. The thermal properties, such as melting temperature, latent heat, were measured by DSC. The results showed that the melting temperatures ranged from 55.5 ^OC to 60.4 ^OC and the latent heat was proportional to the mass percentage of PEG.
