摘要：

Polyethylene glycol (PEG) was selected as a phase-change material (PCM) and the phase-change fibers of its copolymers with polyethylene terephalate (PET), PET-PEG, were successfully prepared by melt spinning. The PET-PEG copolymers have solid-solid phase change characteristics at 10-60 degrees C without obvious liquid substance appearing, while PET/PEG blends will lose their phase-change characteristics since the PEG of the blends may melt and leak under high temperature. By controlling the molecular weight and relavent proportion of PEG added, the phase-change temperature range and the enthalpy can be adjusted.
