Design and development of a cylinder type electrospinning device for the mass production of nanofibers

Electrospinning is a simple, scalable and versatile technique, using strong electrical fields to draw polymer solutions to produce fibers with diameters ranging from micrometers to nanometers that exhibit a high surface area to volume ratio. Electrospun fibers have been the focus of research for applications such a d biomedical, water treatment filter and next-generation energy storage device etc. However, the mass production of electrospun nanofibers is not yet completely established and hence it has to struggle in terms of production cost reduction. Keeping it in mind, in this study we developed a high speed nanofiber production system composed of one meter width cylinder type nozzle block for the mass production of nanofibers. Scanning Electron microscopy (SEM) images and time measurement results showed that our cylinder type mass production system is approximately 80 times more productive than the conventional single nozzle type system. So our system will be able to produce the nanofibers in mass scale and can be effectively applied to various industries, those are in need of large amount of nanofibers.
