Assembly of Oriented Ultrafine Polymer Fibers by Centrifugal Electrospinning
Figure 2
(a) SEM images of aligned straight PS fibers electrospun at conditions of 3.0 kV, 420 rpm, and 2.5 cm. Inserted is a SEM image with larger magnification. (b) Distributions of the degree of alignment () defined by the difference between the angles of orientation () of fibers and the long axis.
