Abstract
The novel form-stable composite phase change materials (PCMs) of crosslinked PEGA and P(PEGA-HAM)/PEG gels were synthesized, which based on PEGA . Using crosslinked PEGA and P(PEGA-HAM)/PEG gels as the working substance , PP/PCM thermo-regulating fibers were prepared by blends via melt spinning respectively. TGA results indicate that the crosslinked form-stable PCMs have good thermal stability. The morphology of the surface of PP/PCM thermo-regulating fibers smooth mainly by SEM. The breaking strength of thermo-regulating fibers first increases and then decreases when increased some content of PCM. DSC results indicate the phase enthalpy of PEGA crosslinked gel and its the blend fibers with PP are 122.97J/g and 13.83J/g, while that of P(PEGA-HAM)/PEG crosslinked networks gel and its the blend fibers with PP are 107.48J/g and 4.62J/g respectively.
