Abstract: The polyethylene glycol (PEG) 6000–cellulose (CELL) composite was prepared by grafting PEG 6000 to CELL chemically and analyzed with fourier transform infrared spectrum analyzer. The spectrum graph indicated that the PEG - CELL had been changed into graft composite. The PEG - CELL composite thermodynamic property was also measured with differential thermal analyzer (DTA). It was found that the PEG-CELL composite exhibited solid-solid phase change behavior. In comparison with PEG 6000, the PEG-CELL composite has lower phase change enthalpy. But the phase change temperature does not change much more. The PEG-CELL composite has good thermal stability during phase transition without sublimation or decomposition. So the PEG-CELL composite can be used as a new kind of solid-solid phase change material for thermal energy storage and temperature control.
