| Abstract: | In this article, a novel process called cylindrical-electrode-assisted solution blowing spinning (CSBS) for producing excellent quality nanofibers with simultaneous electrostatic force and air stretching is reported. The originality of this work is in a new apparatus. With a cylindrical electrode, the solution jets were noncontact charged because of electrostatic induction; this is different from traditional solution-blowing spinning (SBS). Poly(ethylene oxide) nanofibers were fabricated by the CSBS technique for the first time. The scanning electron microscopy results prove that the nanofiber mats produced by CSBS and formed by individual cylindrical-shaped fibers presented a more regular morphology than SBS ones. Compared with that of SBS fibers, the CSBS fiber diameter standard deviation decreased by 21%, and the mean diameter decreased by 6.17%. Their thinner and more uniform fibers may make CSBS fiber webs a better candidate for filtration and other uses compared with SBS ones. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.
