Abstract

See full text

Electrospinning (ES) produces fibers with small cross-sections and high surface area, making them ideal for a multitude of applications. Structures produced using ES methods exhibit a high surface-to-volume ratio, tunable porosity, and controllable composition. ES involves the delivery of a liquid or solid polymer to a spinneret, whereby, an initiated electric field pulls the polymer into micro to nano-scale fibers. Due to the multitude of applications for which polymer fibers can be used, it is desirable to provide an efficient and portable ES device that allows on-demand deposition of polymer materials. The invention that is subject of this patent application is a portable ES device that allows ideal deposition on a substrate regardless of whether that substrate is attached to high voltage or grounded, and regardless of whether or not there is a charged or grounded substrate behind the desired deposition surface.
