  • FOCUSED ROTARY JET SPINNING DEVICES AND METHODS OF USE THEREOF
    Publication number: 20220090300
    Abstract: Systems and methods for focused direction deposition of a micron or nanometer dimension polymeric fiber and materials of such fibers are described herein. Systems and methods employ one or more gas flows to entrain and deflect fibers produced by a rotary jet spinning system forming a focused fiber stream. Some embodiments enable control of alignment and distribution of the fibers with a relatively high fiber throughput.
