| Popis: |
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. |
