Preparation and Performance of Polyethylene Glycol / Polyacrylamide Phase Change Material
This study involved the preparation and characterization of polyethylene glycol (PEG)/ polyacrylamide (PAM) composite as solid-solid phase change materials (PCM). In this study, the polyethylene glycol / polyacrylamide composites as solid-solid phase change material was prepared, and the phase change behavior and crystalline morphology of the phase change materials were investigated using differential scanning calorimeter (DSC) , wide-angle X-ray diffraction (WAXD). Results indicated that the composite remained solid when the weight percentage of PEG was less than 60%. The PEG/PAM composite that exhibited solid-solid phase change behavior can be used as a new kind of phase change material for the shortage of thermal energy and temperature control.
