Development of Nanofibers Before the Age of Nanotechnology: Looking Forward Into the Future Through Looking Back Into Thirty Years of Electrospinning

摘要

Successful commercialization requires three components: 1. Technology 2. Manufacturing and 3. Marketing Donaldsons "Ultra Web" nanofiber introduced in 1981met societys needs for better filtration (marketing) by sub-micron diameter fibers (technology), using then unknown electrospinning. Initial research on electrospinning and early effort on establishing polymer concentration C solution viscosity Cfiber diameter relationship will be discussed. I will discuss a method of reducing shots and improving amount of fibers generated from low viscosity polymer solutions. Related subjects; shape of electrospun fibers and surface roughness will also be discussed. Additional research on modeling and characterization will be discussed.
