الوصف: |
Although it was possible to produce solid–solid phase change materials (SSPCM) by loading phase change materials (PCMs) on supporting materials, the enthalpy of PCMs was always reduced. To address this issue, poly(hexadecyl acrylate) (PHDA) was immobilized to cellulose nanocrystal (CNC) through grafting and intermolecular forces, which held good crystallization promotion performance via in situ free radical polymerization. CNC was grafted with reactive vinyl, which functioned as a reactive site for polymerizing PHDA. The chemical structure, morphology, and thermal properties of CNC before and after modification were characterized with Fourier transformation infrared spectroscope (FT-IR), scanning electron microscope (SEM), thermogravimetric analyzer (TGA), and differential scanning calorimeter (DSC). The prepared SSPCM was found to have good form stability and a high melting enthalpy (139.7 J/g), which was significantly higher than pure HDA. After 100 heating and cooling cycles, there was no discernible change in the melting and crystallization enthalpies of the SSPCM, implying that it had outstanding thermal reliability and shape stability. |
