We describe simple procedures for fabricating single polymeric helical nanofibers and
converting these helical nanofibers into linearly oriented nanofibers using a modified electric
field in an electrospinning system. Helical structures were made from a solution of
poly2-acrylamido-2-methyl-1-propanesulfonic acid in water and ethanol by bending instability of
electrospinning. By newly introducing parallel subelectrodes that change an ordinary electric field
into a splitting electric field, it was elucidated that the tensional electrostatic forces caused by a
modified electric field have an important effect on the transformation of helical structures.
