Article Preview

Octadecylated poly (vinyl alcohol) (PVA-C18) comb-like polymer was prepared through the reaction between PVA and 1-bromooctadecane via O-alkylation method. The structure, thermal properties and packing mode of PVA-C18 comb-like polymer were detailed investigated with Fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC), and X-ray diffraction (XRD). The results show that octadecyl side chains had been successfully grafted onto PVA backbones, and PVA-C18 comb-like polymer exhibit the better thermal storage properties with enthalpy of 29.3kJ/mol , indicated that it is one kind of solid-solid phase change materials.
