What copolymer of ethylene and vinyl acetate can nanofibers be made of?
Nanofiber Nanofibers are fibers with diameters in the nanometer range. Nanofibers can be generated from different polymers and hence have different physical properties and application potentials. Examples of natural polymers include collagen, cellulose, silk fibroin, keratin, gelatin and polysaccharides such as chitosan and alginate. Examples of synthetic polymers include poly(lactic acid) (PLA), polycaprolactone (PCL), polyurethane (PU), poly(lactic-co-glycolic acid) (PLGA), poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), and poly(ethylene-co-vinylacetate) (PEVA). Polymer chains are connected via covalent bonds. The diameters of nanofibers depend on the type of polymer used and the method of production. All polymer nanofibers are unique for their large surface area-to-volume ratio, high porosity, appreciable mechanical strength, and flexibility in functionalization compared to their microfiber counterparts.
Ultrasuede Ultrasuede is the trade name for a synthetic microfiber fabric invented in 1970 by Dr. Miyoshi Okamoto, a scientist working for Toray Industries. In Japan it is sold under the brand name Ecsaine. It's an ultra-microfiber. It is often described as an artificial substitute for suede leather. The fabric is multifunctional: it is used in fashion, interior decorating, automotive and other vehicle upholstery, and industrial applications, such as protective fabric for electronic equipment. It is also a very popular fabric in the manufacture of footbags (also known as hacky sacks) and juggling balls. Other manufacturers such as Sensuede and Majilite also produce similar product lines of synthetic microfiber suede construction.
