摘要/Abstract

摘要： 将相变材料PEG掺杂到高聚物PA6中去，通过静电纺丝制备相变调温纳米纤维。通过扫描电镜、红外光谱、热分析仪以及织物强力仪等测试方法对相变纳米纤维的结构与性能进行表征。结果表明：PEG的共混改善了纺丝液黏度，随着PEG共混比例的提高，纳米纤维的直径提高；PA6与PEG有氢键结合，随着PEG共混比例的提高，相变纳米纤维的熔融温度和熔融焓值逐渐增大，相变纳米纤维具有良好的蓄热调温性能；随着相变材料PEG共混比例的提高，相变纳米纤维的强力有一定下降。结论：该纳米纤维是一种良好的调温储能材料。

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.

Key words: phase change∕temperature regulating, electrospinning, nanofiber, PA6, PEG
