Nanofiber mats have received considerable attention from researchers in the field of particulate protection. In this study, polyvinylidene fluoride (PVDF) nanofiber mats were prepared on a large scale by a solution blowing process, and then crosslinked 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. Results show that the addition of TMPTA and UV treatment decreased the diameter of the nanofibers and enhanced the mechanical properties, air permeability, and moisture permeability. Nanofiber mats show higher filtration and lower filtration resistance compared with a commercial product. Furthermore, the nanofiber mats were bonded with Nylon 6 fabric, which showed good performance as a novel functional layer in protective clothing.

纳米纤维垫在微粒保护领域受到了研究人员的相当大的关注。在这项研究中，聚偏二氟乙烯（PVDF）纳米纤维垫是通过溶液吹塑工艺大规模制备的，然后使用三羟甲基丙烷三丙烯酸酯（TMPTA）作为交联剂通过紫外线（UV）辐射进行交联。评估了纳米纤维垫的结构，形态，机械和热性能以及防护性能。结果表明，TMPTA和紫外线处理的加入减小了纳米纤维的直径，并增强了机械性能，透气性和透湿性。与商业产品相比，纳米纤维垫具有更高的过滤性能和更低的过滤阻力。此外，纳米纤维垫与尼龙6织物粘合在一起，
