Abstract
Electrospinning employs electrostatic force to stretch a charged polymer
solution jet and is capable of producing submicron diameter fibers. There has
been considerable interest in electrospun fibers due to the ease with which
nanometer-scale fibers can be produced from a wide range of polymers. In many
applications, the average electrospun fiber diameter and its uniformity have
important implications for the product's performance and process economics.
Thus, it is desirable to develop electrospinning capability to achieve consistent and controllable fiber diameters. However, the current state-of-the-art
electrospinning process results in varying diameter both during a run and runto-
run. In addition, the relations of the process and material parameters to the
resulting fiber diameter characteristics are not completely understood.
This research focuses on understanding what determines the fiber
diameter distribution and developing the knowledge base for design of a fiber
diameter control system in order to achieve a consistent and repeatable process. [TRUNCATED]
