新冠肺炎疫情导致口罩等个人防护用品迫在眉睫地短缺。为了解决这一短缺问题，口罩的新灭菌或去污程序正在迅速开发和应用。干热和蒸汽灭菌过程易于扩展，并允许处理大样本，因此可能提供快速有效的去污途径，这可能显著缓解在新冠肺炎等大流行期间全球对防护口罩迅速增长的需求。本研究采用扫描电子显微镜、接触角、X射线衍射仪、X射线光电子能谱、拉曼光谱等分析手段，研究了热处理对市售3M 8210 N95口罩和VWR高级防护口罩的影响。这项研究的独特之处在于使用了位于布鲁克海文国家实验室国家同步加速器光源II的基于同步加速器的原位和OPERANDO软X射线光谱(IOS)光束线(23-ID-2)，用于近边X射线吸收光谱(NEXAFS)。热回收程序对N95和外科口罩的结构完整性和表面化学的影响通过一套结构和化学表征技术进行了评估。
The COVID-19 pandemic resulted in imminent shortages of personal protective equipment such as face masks. To address the shortage, new sterilization or decontamination procedures for masks are quickly being developed and employed. Dry heat and steam sterilization processes are easily scalable and allow treatment of large sample sizes, thus potentially presenting fast and efficient decontamination routes, which could significantly ease the rapidly increasing need for protective masks globally during a pandemic like COVID-19. In this study, a suite of structural and chemical characterization techniques, including scanning electron microscopy (SEM), contact angle, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Raman were utilized to probe the heat treatment impact on commercially available 3M 8210 N95 Particulate Respirator and VWR Advanced Protection surgical mask. Unique to this study is the use of the synchrotron-based In situ and Operando Soft X-ray Spectroscopy (IOS) beamline (23-ID-2) housed at the National Synchrotron Light Source II at Brookhaven National Laboratory for near-edge X-ray absorption spectroscopy (NEXAFS). The impact of heat recycling procedures on the structural integrity and surface chemistry of the N95 and surgical masks was assessed by a suite of structural and chemical characterization techniques.
