Since the outbreak of the COVID-19 pandemic, most countries have recommended their citizens to adopt social distance, hand hygiene, and face mask wearing. However, wearing face masks has not been well adopted by many citizens. While the reasons are complex, there is a general perception that the evidence to support face mask wearing is lacking, especially for the general public in a community setting. Face mask wearing can block or filter airborne virus-carrying particles through the working of colloid and interface science. This paper assesses current knowledge behind the design and functioning of face masks by reviewing the selection of materials, mask specifications, relevant laboratory tests, and respiratory virus transmission trials, with an overview of future development of reusable masks for the general public. This review highlights the effectiveness of face mask wearing in the prevention of COVID-19 infection.
自新冠疫情爆发以来，大多数国家都建议本国公民保持社交距离、勤洗手并佩戴口罩。然而，许多公民并未很好地遵守佩戴口罩的建议。尽管原因复杂，但普遍认为缺乏支持佩戴口罩的证据，尤其是对于社区环境中的普通民众而言。佩戴口罩可通过胶体和界面科学原理阻挡或过滤空气中携带病毒的颗粒。本文通过回顾材料选择、口罩规格、相关实验室测试及呼吸道病毒传播试验，评估了当前关于口罩设计与功能的知识，并概述了面向普通大众的可重复使用口罩的未来发展。这篇综述强调了佩戴口罩在预防新冠感染方面的有效性。
