Preparation and property of phase change fiber by electrospinning

The microcapsules with the function of phase transition temperature were added to the spinning solution, and the nano-fibers with phase transition function were spun by electrospinning. These fibers were characterized by scanning electron microscopy, differential scanning calorimetry and ther-mogravimetric analyzer. The results show: the fibers are flat and smooth and the diameter of fiber increases with the increase of the content of microcapsules; the fiber has a certain phase change function, but the phase change temperature and the phase change enthalpy have nothing to do with the content of the microcapsules; the fiber has good thermal stability. © 2018 Deutscher Fachverlag GmbH.
