Abstract:A novel phase-change composite based on hexadecanol and dye-linked polyurethane (dye-PU) was obtained in the present paper. Hexadecanol functions as a phase-change material (PCM) while dye-PU functions as both a supporting material and PCM, unlike in previous phase-change composites where it is used only as a general supporting material. FT-IR, XRD, DSC, and TG were employed to determine the structure and basic properties of the composite. The phase change enthalpy of the composite reached 229.5 J/g, which was higher than that reported for most form-stable PCMs. The maximum weight percentage of hexadecanol that could be added to the composite without leakage was 63.8%. The linked dye absorbed visible light and converted it into thermal energy that could be stored by the phase-change material. (C) 2015 Elsevier B.V. All rights reserved.
