Preparation and performance of novel polyvinylpyrrolidone/polyethylene glycol phase change materials composite fibers by centrifugal spinning

Polyethylene glycol acrylate-grfat-Cellulose-acrylate (PEGA-g-CEA) has been synthesized as side-chain-type solid-solid phase change materials for thermal energy storange through graft copolymerization. The composition and structure of the grafts and cellulose, phase transition properties and morphology of grafts were investigated by Fourier transform infrared spectrometer (FTIR), differential scaanning calorimentry (DSC) and optical microscopy. The results show that the polyethylene glycol (PEG) successfully grafted onto the cellulose macromolecule, and the solid-solid phase change materials with a certain phase transformation ability were obtained through this experiment.

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.

Change Material

In the present study, a novel phase change material polyethylene glycol (PEG) / titanium dioxide (TiO2) composite was prepared and characterized by DSC, FT-IR, SEM and WAXD. The melting temperature and latent heats of PEG/ TiO2 was determined using differential scanning calorimeter (DSC). The interactions between PEG and TiO2 were analyzed by Fourier transform infrared (FT-IR) spectroscopy. In the form-stable blends, PEG acted like phase change material when the TiO2 served as supporting material. SEM and WAXD tests were performed to investigate the crystalline morphology. PEG/ TiO2 composite were proven a good polymeric phase change heat storage material.
