What are the most important measures in understanding nanofibers?
There are many important measurements to consider when evaluating a nanofiber solution, be it as part of a standard rolled good, as a surface coating or as a free standing nanofiber mat (or nanofiber membrane). Both the individual nanofibers and the webs formed from the nanofibers require accurate measurement and description in terms of their diameter, uniformity, length, web thickness, web structure, web size, fiber packing density, and production speed. Nanofiber diameter: Electrospinning routinely results in fibers with diameters ranging from 500 nm to 50 nm, though there is some difficulty in obtaining smaller sizes for some polymer systems. Larger diameter beads and other structures can be created as needed to add tertiary morphology to the nanofiber web. Nanofiber uniformity: Uniformity is usually defined in terms of standard deviation of the fiber diameter across the nanofiber web. This can vary broadly by production methodology, but a fiber diameter standard deviation of less t
