Face masks are an effective protection tool to prevent bacterial and viral transmission. However, commercial face masks contain filters made of materials that are not capable of inactivating either SARS-CoV-2. In this regard, we report the development of an antiviral coating of polyurethane and Copper nanoparticles on a face mask filter fabricated with a spray technology that is capable of inactivating more than 99% of SARS-CoV-2 particles in 30 min of contact.
口罩是预防细菌和病毒传播的有效保护工具。然而，商业口罩的过滤器由不能灭活 SARS-CoV-2 的材料制成。在这方面，我们报告了一种抗病毒涂层的开发，该涂层由聚氨酯和铜纳米粒子组成，涂覆在口罩过滤器上，该过滤器是通过喷涂技术制造的，在接触 30 分钟内能够灭活超过 99%的 SARS-CoV-2 颗粒。
