摘要
Many kinds of electrospinning methods have emerged and been well investigated in the past two decades in the pursuer of nanofiber preparation and its scaling-up. Among the electrospinning methods, melt electrospinning, as a non-solvent route, has draw great attention in recent years since its high yield and safety. However, there was few work has been done on the mass production of nanofiber and yarn production by this polymer melt based method. On this basis, a melt differential electrospinning method without needles was proposed, by which the single nozzle can yield two orders of magnitude more than the capillaries did and nanofiber production in kilo scale was realized. A simple solution for yarn production was also introduced with narrow diameter distribution. Larger scale production can be easily performed by modular designing and assembling. For example, Polypropylene nanofiber with diameter around 500 nm and Poly Lactic Acid(PLA) nanofiber with diameter around 550 nm can be achieved by this method. Based on this principle, complete commercial techniques and equipments have been developed, and applications of as-spun fibers in air filtration, oil spill recovery and water treatment, etc, are promising.
