The outbreak of unknown viral pneumonia in Wuhan China in December 2019 led to a new coronavirus (SARS-CoV-2), which attracted worldwide attention, with the related COVID-19 disease quickly becoming a global pandemic. In about 5 months, this disease has led to ~ 4 million cases and claimed more than 200 k deaths as a result of its highly contagious nature. The present understanding is that SARS-CoV-2 is a type of influenza virus that can be transmitted through respiratory droplets and aerosols; Lewis (Nature 580:175, 2020). The primary methodology to prevent the spreading of this disease has been "social distancing" and usage of personal protective equipment (PPE) at the front lines of healthcare and other critical operations. The scale of the disease has led to unprecedented demand for PPEs and increased functionality of the same. This paper focuses on improving PPE functionality in a scalable manner by surface treatment and coating with appropriate materials and other functional enhancements, such as exposure to UV rays or other sterilizing agents (e.g., hydrogen peroxide).
2019年12月在中国武汉爆发的不明原因病毒性肺炎导致了一种新型冠状病毒（SARS-CoV-2），引起了全球关注，与之相关的COVID-19疾病迅速成为全球大流行。在大约5个月的时间里，这种疾病因其高度传染性导致了约400万例病例，并造成了超过20万人死亡。目前的认识是，SARS-CoV-2是一种可通过呼吸道飞沫和气溶胶传播的流感病毒；刘易斯（《自然》580:175，2020）。预防这种疾病传播的主要方法是“社交距离”以及在医疗保健和其他关键操作的前线使用个人防护装备（PPE）。该疾病的规模导致了对个人防护装备前所未有的需求，并提高了其功能。本文重点介绍通过表面处理和用适当材料涂层以及其他功能增强措施（如暴露于紫外线或其他消毒剂（如过氧化氢））以可扩展的方式提高个人防护装备的功能。
