Green copolymers as phase change material were prepared by grafting polyethylene glycol (PEG) onto a rigid molecular skeleton of cellulose nanocrystals (CNs), and their thermal properties were studied by thermal delay method and differential scanning calorimetry. The influences of the CNs on the thermal conductivity behavior and thermal energy storage capacity of the copolymers were evaluated. As expected, a great enhancement on thermal conduction can be achieved by introducing CNs.
