Abstract

Helical structures have been fabricated from a solution of poly(2-acrylamido-2-methyl-1-propane sulfonic acid) (PAMPS) in water and ethanol by the whipping instability of a jet in a conventional electrospinning system. The simple modification of the electrospinning system involved introducing two parallel subelectrodes, which enabled the transformation of helical nanofibers into linearly oriented nanofibers due to the tensional forces caused by the modified electric field. This means that the tensional forces caused by the modified electric field had an important effect on linearizing the helical structures. Therefore, a technique using modified electric fields can play a significant role as an intermediary between helical structures and one-dimensional linear structures.
