Embodiment Construction

[0030] simply put:

[0031] figure 1 is a non-limiting diagram schematically illustrating a typical electrospinning process. A typical electrospinning setup consists of a syringe pump, a syringe with a needle, a high voltage power supply, and a collector. Currently, a single rotating or flat target disk, a pair of charged collector bars, has been used as a fiber collector.

[0032] figure 2 is a non-limiting diagram schematically illustrating the method of the invention. The embodiment shown in the diagram uses the path of the electromagnetic field generated by the potential difference between the charged needle and the rotating auxiliary metal disk obtained using a high powered voltage source to capture, deposit and orient the fibers on the substrate. The device shown includes a syringe needle, DC motor, blunt bolt, and front insulating washer. Use a linear gantry to reciprocate the collector.

Abstract

A method for separating out nano-scale fiber threads from many fiber branches and controlling alignment and deposition of the fiber threads on a substrate, comprising: electrospinning at least synthetic polymer fiber streams from an electrically charged syringe needle; controlling the fiber using at least one electrically charged metallic disk rotating about an axis positioned below the needle; capturing the fiber using electrically grounded collector; extracting a single or plurality of fiber branch threads from the fiber streams, wherein the single or plurality of fiber branch threads is attracted to and intercepted by the collector shape, and depositing the single or plurality of fiber branch threads as substantially aligned fiber on the collector.

Description

[0001] Statement Concerning Rights to Inventions Made Under Federally Sponsored Research or Development [0002] This invention was made with government support from OK-INBRE (Oklahoma IDeA Network of Biomedical Research Excellence). OK-INBRE was supported by the National Institute of General Medicine of the National Institutes of Health through grant number 8P20GM103447. The government has certain rights in this invention. technical field [0003] The present invention relates generally to the field of polymer fiber production. More specifically, the present invention relates to the deposition of aligned fibers of micron to nanometer sized diameters from branched polymers on metal implants of various shapes and other types of substrates during the electrospinning process. Background technique [0004] The basic concept of electrospinning (or electrospinning) polymers to form fibers of extremely small diameter was first patented by Anton Formhals (US Patent No. 1975504). ...
