Abstract: Aim of this paper is to prepare PA6/PEG phase change nanofiber was by means of adding phase change material PEG into PA6 via electrospinning. Structure and properties of the PA6/PEG phase change nanofiber were characterized by means of SEM, FTIR, thermal analyser, and electronic strength tester. The results show that the PEG can improve the viscosity of the electrospinning. The diameter of the nanofiber increases with the increase of the blended ratio of the PEG. There are hydrogen bonds between the PA6 and PEG. The melting temperature and enthalpy of the phase change nanofiber increase with the increase of the blended ratio of the PEG. PA6/PEG nanofibers have excellent thermal-regulating properties. Breaking strength of the phase change nanofiber decreases with the increase of the blended ratio of the PEG. Conclusion of this research is that the PA6/PEG nanofiber is an excellent thermal-regulating material.
