Scale space filtering properties

The idea of using polymer nanofiber as affinity membrane is based on the fact that the polymer nanofibers deposited on the collector during electrospinning assemble into a membranelike nonwoven fiber mesh. This electrospun nonwoven mesh possesses properties such as high porosity, micron-scaled pore size, and high interconnectivity of the interstitial space. Above all, the nanoscaled fiber diameter gives rise to an increased surface area as compared with the conventional nonwoven filter media composed of currently available textile fibers with typical diameters of several microns. A large surface area-to-volume ratio is one of the most important...
