Ac Electrospinning: Device for Controlled Production Of Planar, Singlelayer Nanofiber Plume

Popis výsledku v původním jazyce

The work focuses on the development of a linear electrode for the production of flat nanofibrous material by spinning a polymer solution using the AC electrospinning technique. Current spinning electrodes for AC electrospinning are characterized by a working surface with a overcritical electric field intensity, from which polymer jets and subsequent nanofibers are created in all directions. A spatial, hollow nanofibrous plume is created by the natural periodic interconnection of fibers in the area of the virtual collector.By the geometrically modified electrodes with the help of simulation tools for electric field analysis, it is possible to efficiently modify the geometry and the working surface of the electrode so that the nanofibers are formed only in a single plane, thereby eliminating the negative effects of the spatial nanofibrous plume. Based on the analyses, electrodes capable of continuous operation producing nanofibers in the single plane and in the desired direction producing a planar nanofiber structure are developed and tested.
