Structure and properties of PA6 /PEG phase change and temperature regulating nanofibers

PA6 /PEG phase change and temperature regulating nanofibers were prepared by means of adding phase change material PEG into PA6 via electrospinning. Structure and properties of the PA6 /PEG phase change nanofibers were characterized by means of SEM,FT-IR,thermal analyser,and electronic strength tester. The results showed that polyblending of PEG improves the spinning solution viscosity. With the increase of polyblend ratio of PEG,the diameter of the nanofibers increases,and the melting temperature and enthalpy of the phase change nanofibers increase,but the breaking strength decreases a little. The hydrogen bonding of PA6 with PEG is observed. PA6 /PEG nanofibers have excellent thermal accumulation and temperature regulating properties.
