Abstract

In this paper, we report a simple method to separate immobile charges into polarization charges and trapped charges and successfully prepare electrospun polyacrylonitrile fibers only containing polarization charge. The amount of surface polarization charges and trapped charges were +5.34 nC/g and −2.98 nC/g, respectively. We also tried to explain the mechanism of formation and location of immobile charges by using a model of a parallel plate capacitor, and to track the route and location of charges. Additionally, we investigated the influence of residual solvent, a water bath and the temperature of the water bath on the immobile charges.
