Abstract

Melt-blown polymer fiber materials are frequently used in the face mask manufacturing. In the present work, a melt-blown polypropylene tape was modified by silver nanoparticles using chemical metallization. The silver coatings on the fiber surface consisted of crystallites 4-14 nm in size. For the first time, these materials were comprehensively tested for antibacterial, antifungal and antiviral activity. The silver-modified materials showed antibacterial and antifungal activities, especially at high concentrations of silver, and were found to be efficient against the SARS-CoV-2 virus. The silver-modified fiber tape can be used in the face mask manufacturing and as an antimicrobial and antiviral component in filters of liquid and gaseous media.

摘要

熔喷聚合物纤维材料常用于口罩制造。在本工作中，采用化学镀法用银纳米颗粒对熔喷聚丙烯胶带进行了改性。纤维表面的银涂层由尺寸为4 - 14纳米的微晶组成。首次对这些材料进行了抗菌、抗真菌和抗病毒活性的全面测试。银改性材料表现出抗菌和抗真菌活性，尤其是在高银浓度下，并且被发现对SARS-CoV-2病毒有效。银改性纤维胶带可用于口罩制造，并作为液体和气体介质过滤器中的抗菌和抗病毒成分。
