Wet-Spinning and Electrospinning of Modified Poly(vinyl alcohol) Fiber with Reduced Wettability

Resumo

Modified poly(vinylalcohol) (PVA) fibers with increased anti-adhesive properties could be produced by spinning from solutions containing latex modifiers [copolymer of 1,1-dihydroperfluoroheptyl methacrylate and 1,1,5-trihydroperfluoroamyl acrylate (LFM-3K) and the F-containing Oleophobol S] and the F-containing surfactant POF-9. The rheological properties of the PVA spinning solutions with the added F-containing components were studied. The anti-adhesive properties of wet-spun fibers and fibrous material produced by electrospinning depended on the type of polymer, nature of additive, and size of latex particles. The structures of the modified PVA fibers were investigated using atomic force microscopy.
