摘要
该项目涉及医疗保健和社会援助/免疫、传染病和皮肤病
预防(HSAxIID),战略目标3:减少职业免疫、传染和皮肤病。
中间目标是预防传染病传播,研究重点是个人
保护设备(3.3.H)。2019冠状病毒病(COVID-19)大流行主要通过以下途径传播:
携带病毒的飞沫和短程气溶胶。N95呼吸器是一种必要的个人防护装备,
抗击新冠肺炎由于担心呼吸器上的病毒积累会导致污染物感染,
使消毒器尽可能少受污染,以更好地保护医护人员。为了解决这个
关键挑战,该申请提出将高度氟化的氧化石墨烯喷涂到外表面上
N95呼吸器喷涂为N95呼吸器增加了额外的多孔纳米结构。高度
氟化氧化石墨烯纳米结构涂层具有优异的超疏水性。的

英文摘要
Title: Durable Self-cleaning Fluorinated Graphene Oxide Coated N95 Respirators
Abstract
This project addresses the healthcare and social assistance/Immune, Infectious and Dermal Disease
Prevention (HSAxIID) with the strategic goal 3: reduce occupational immune, infectious, and dermal disease.
The intermediate goal is to prevent the infectious disease transmission with research focus on personal
protection equipment (3.3.H). The coronavirus disease 2019 (COVID-19) pandemic is primarily transmitted by
virus laden droplets and short-range aerosols. N95 respirator is an essential personal protection equipment to
combat COVID-19. Due to concerns over virus accumulation on the respirator for fomite infection, it is crucial to
make the respirators less contaminated as possible to better protect the healthcare workers. To address this
critical challenge, this application proposes to spray-coat highly fluorinated graphene oxide onto the outer surface
of the N95 respirator. Spray coating adds an additional porous nanostructure to the N95 respirator. The highly
fluorinated graphene oxide nanostructured coating possesses the exceptional superhydrophobicity. The
superhydrophobicity exhibits extreme water repellence and is hypothesized to make the N95 respirators less
contaminated by repelling the respiratory droplets off the respirator’s surface instantaneously. In addition, the
extraordinary robustness of graphene oxide to various environmental challenges is supposed to address the
durability issue associated with frequently reusing. The specific aims are, therefore, to test the highly fluorinated
graphene oxide nanostructured coating is (1) capable of repelling respiratory droplets while maintaining the
aerosol filtration efficiency; (2) capable of preventing the accumulation of SARS-CoV-2 virus on the N95
respirators. The outputs of the project will be journal articles, reports, and conference proceedings and
presentations. The intermediate outcomes will include citations in the literature and adoption of the technology
developed in the project. The end outcomes will be better protection of healthcare workers in terms of preventing
transmission of work-related infectious diseases among workers by translating this new technology to the
healthcare & social assistance sector, addressing Research to Practice (r2p).
