        UV-crosslinked Solution Blown PVDF Nanofiber Mats for Protective Applications

        Ya Liu,Xueming Wang,Nana Li,Xiaoyin Wang,Lei Shi,Enjie Wu,Rui Wang,Mingjing Shan,Xupin Zhuang 한국섬유공학회 2020 Fibers and polymers Vol.21 No.3

        Nanofiber mats have received considerable attention from researchers in the field of particulate protection. In thisstudy, polyvinylidene fluoride (PVDF) nanofiber mats were prepared on a large scale by a solution blowing process, and thencrosslinked by ultraviolet (UV)-radiation using trimethylolpropane tri-acrylate (TMPTA) as a crosslinker. The structure,morphology, mechanical and thermal properties, and protective performance of the nanofiber mats were evaluated. Resultsshow that the addition of TMPTA and UV treatment decreased the diameter of the nanofibers and enhanced the mechanicalproperties, air permeability, and moisture permeability. Nanofiber mats show higher filtration and lower filtration resistancecompared with a commercial product. Furthermore, the nanofiber mats were bonded with Nylon 6 fabric, which showedgood performance as a novel functional layer in protective clothing.
