Abstract

The present disclosure describes methods and apparatus for the controlled production of fibers, such as nanofibers, with desired lengths and/or diameters. As a result, the aspect ratio (the ratio of fiber length to fiber width) of the fibers can be controlled as desired. Such methods and apparatus allow the production of fibers for use in current fiber applications and provide fibers for use in new applications as well. Furthermore, the present disclosure describes fibers, such as nanofibers, having desired lengths, diameters and/or aspect ratios as well as fiber constructs comprising such fibers for use in a variety of applications.
