| Abstract: | In: The morphologically stable phase change material(PCMs) was prepared by adsorption of polyethylene glycol(PEG) which was as energy storage medium with porous nanomaterials. Then, regenerative thermostat fibers of polyamide 6 were prepared by melt spinning with polyamide 6(PA6) as a matrix. The structure and properties of the fibers were characterized by field emission scanning electron microscopy, differential scanning calorimetry, thermogravimetric analysis and powder X-ray diffraction. The results showed that enthalpy of regenerative thermostat fibers of PA6/PCMs prepared by melt spinning was 19.01 J/g, which was expected to be widely used in aviation, military combat clothing and civilian clothing. |
