Confinement effect of SiO2 framework on phase change of PEG in shape-stabilized PEG/SiO2 composites

A Novel Synthesis Method of Porous Calcium Silicate Hydrate Based on the Calcium Oxide/Polyethylene Glycol Composites

“…The microstructures are evaluated by Fourier transformed infrared spectroscopy (FT-IR, IR Prestige-21FT-infrared spectrometer, Shimadzu, Japan). when the pH value is over 13.0 [26][27][28]. This result can be verified according to the fraction formula of H 2 SiO 3 , HSiO 3 − and SiO 3 2− under the given pH value as follows:…”

Effect of concentrations of plasticizers on the sol-gel properties developed from alkoxides precursors

“…However, it was not possible to evaluate a change in the crystalline fraction of the hybrid films, since it is not possible to quantitatively compare the change in the intensity of the XRD peaks. Similar results were observed by Yang et al [19] in their study on the effect of the concentration of PEG 1500 in composites with SiO 2 . The XRD showed that PEG 1500 has the crystalline structure with typical diffraction peaks at 19° and 24° (2θ).…”

Thermal analysis and non‐isothermal kinetics of poly(ethylene glycol) with different molecular weight

“…Polyethylene glycol (PEG), a non‐toxic and non‐corrosive polymer, has recently been studied as a promising thermal energy storage material given its relatively large latent heat, suitable melting point, resistance to corrosion, wide melting point range, and chemical stability . It can be used in many applications including industrial heat utilization, electronic device management, and protection as well as active and passive heating or cooling of buildings .…”
