Thermal properties of chemically modified cellulose with solid-solid phase change

摘要

Phase change materials (PCMs) can promote the utilizatio ratio of energy. In our laboratory, the chemical bonding method was applied to graft PEG (polyethylene glycol) chain onto CDA (cellulose diacetate) skeleton by means of TDI-80 (toluene-2,4-diisocyanate), and thus a new kind of PCM was prepared.
