A new kind of shape-stabilized phase change materials

Based on the lowest melting point and Schroeder’s theoretical calculation formula, nanomodified organic composite phase change materials (PCMs) were prepared. The phase transition temperature and the latent heat of the materials were 24 °c and 172 J/g, respectively. A new shape-stabilized phase change materials were prepared, using high density polyethylene as supporting material. The PCM kept the shape when temperature was higher than melting point. Thus, it can directly contact with heat transfer media. The structure, morphology and thermal behavior of PCM were analyzed by FTIR, SEM and DSC.
