摘要: Nanoflower-like wrinkled mesoporous silica (NFMS) was prepared for further application as the carrier of polyethylene glycol (PEG) to fabricate new, shape-stabilized phase change composites (PEG/NFMS); NFMS could improve loading content PEG in PEG/NFMS. To investigate properties PEG/NFMS, characterization approaches, such scanning electron microscopy (SEM), transmission (TEM), Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), thermal gravimetric analysis (TGA), Brunauer-Emmett-Teller (BET) analysis, and differential calorimetry (DSC), were carried out. The results illustrated that completely adsorbed by physical adsorption, nanoflower-like did not affect crystal structure PEG. As reported DSC test, although had a restriction influence on activity molecules, melting binding enthalpies PEG/NFMS reach 136.6 J/g 132.6 J/g, respectively. In addition, TGA curves demonstrated no evident weight loss observed from 20 °C 190 revealed remarkable stability. These indicated is potential organic material preparation composites.
