COVID-19 belongs to a typical class of viruses that predominantly affects the human respiratory system, thereby proving to be fatal to many. The virus, along with other air pollutant particulates poses a severe threat to the human respiratory organs. Since the most common transmission mode is respiratory fomites and aerosol particulates, it is necessary to prevent their ingression through a mask. The primary use of masks is to prevent aerial particulates. This paper reveals the development of masks with air filters coated with functionalized graphene (fG) mounted on a 3D-printed facial mask replica. The fused deposition modeling (FDM) process is used for fabricating the facial mask replica. fG associated with nanosheets has an additional adsorbing capacity with a high surface area to volume ratio. fG coat is used over a polypropylene (PP) cloth through a dip coating method to enhance the antiviral and antimicrobial properties. The quality of fG was investigated through Raman spectroscopy and other characterization techniques such as SEM, XRD, and FTIR, which were used for visual interpretation of distributions of fG on a polypropylene (PP) fabric. Fabricated fG coated MB filters show 98.2% of bacterial filtration efficiency with 1.10 mbar of breathing resistance. The efficacy of the fG coated filter was tested against SARS-CoV-2 viral particles, which showed a complete arrest of viral transmission at the fG coated layer.

COVID-19 属于典型的一类病毒，主要影响人类呼吸系统，因此被证明对许多人是致命的。该病毒以及其他空气污染物颗粒对人体呼吸器官构成严重威胁。由于最常见的传播方式是呼吸道污染物和气溶胶颗粒，因此有必要防止它们通过面罩进入。口罩的主要用途是防止空气中的颗粒物。本文揭示了带有空气过滤器的面罩的开发，该过滤器涂有功能化石墨烯 (fG)，安装在 3D 打印的面罩复制品上。熔融沉积建模 (FDM) 工艺用于制造面膜复制品。与纳米片相关的 fG 具有额外的吸附能力，具有高表面积与体积比。fG 涂层通过浸涂方法在聚丙烯 (PP) 布上使用，以增强抗病毒和抗菌性能。通过拉曼光谱和其他表征技术（如 SEM、XRD 和 FTIR）研究 fG 的质量，这些技术用于对聚丙烯 (PP) 织物上 fG 的分布进行目视解释。制造的 fG 涂层 MB 过滤器显示 98.2% 的细菌过滤效率和 1.10 毫巴的呼吸阻力。针对 SARS-CoV-2 病毒颗粒测试了 fG 涂层过滤器的功效，结果表明 fG 涂层完全阻止了病毒传播。用于对聚丙烯 (PP) 织物上 fG 分布的视觉解释。制造的 fG 涂层 MB 过滤器显示 98.2% 的细菌过滤效率和 1.10 毫巴的呼吸阻力。针对 SARS-CoV-2 病毒颗粒测试了 fG 涂层过滤器的功效，结果表明 fG 涂层完全阻止了病毒传播。用于对聚丙烯 (PP) 织物上 fG 分布的视觉解释。制造的 fG 涂层 MB 过滤器显示 98.2% 的细菌过滤效率和 1.10 毫巴的呼吸阻力。针对 SARS-CoV-2 病毒颗粒测试了 fG 涂层过滤器的功效，结果表明 fG 涂层完全阻止了病毒传播。
