Abstract
Polymer nonwoven materials based on polypropylene are the basis for the creation of protective medical masks. Modification of the filter layers has been performed by electron-beam deposition from the active gas phase formed by the electron-beam dispersion of PTFE. The filtration efficiency was investigated by two indicators: the PFE with a diameter of 2.5 $\mu$m (PM2.5), BFE in accordance with GOST R 58396-2019 for three-layer combinations of nonwovens, the inner layer of which had a modified coating. An increase in the filtration efficiency for both indicators was observed for all samples, which is associated with physicochemical changes of the surface of the active layer.
以聚丙烯为基础的高分子非织造材料是制造防护医用口罩的基础。利用聚四氟乙烯的电子束色散形成的活性气相进行电子束沉积，对滤层进行了改性。通过两项指标考察过滤效率:直径为2.5 μ m (PM2.5)的PFE和符合GOST R 58396-2019的三层非织造布组合的BFE，内层有改性涂层。两种指标的过滤效率在所有样品中都有所提高，这与活性层表面的物理化学变化有关。
