In this study, we introduced novel electro-spinning method for lab-scale mass production of nano-sized polymeric fiber. Although multi-needle system was used for mass-production in general, it is still challenging task to obtain mass-amount of nanofibers because the multi-needle systems has electrostatic interaction between needles which prevent to form excellent nano-fiber. In addition, general needleless system contains several limitations because the system require higher supplied voltage. Here, we designed the helically probed rotating cylinder to the mass-production of nanofibers by electrospinning. Not only the helical probed cylinder could overcome the limitation of general electrospinning but also could be processed in lower supplied voltage. Furthermore, the helical probed system provides versatility of selecting solvent and polymer for electrospinning and can be applied to many applications which is not possible to be processed by general needle and needleless based methods. |
