Filtering facepiece respirators (FFR) play an indispensable role in protecting people from potential exposure to hazardous airborne contaminants, such as coronaviruses and bacteria, during this COVID-19 pandemic. However, most FFP are single use for 8 hours or less and must be disposed afterwards due to contamination, causing significant shortage of FFR for the pubic and devastating harm to the environment. To address these challenges, Dr. Jian Liu's team at the University of British Columbia, in collaboration with Toronto-based Myant Inc., aims at developing selfinfecting and reusable consumer-grade facemasks that are suitable for everyday use by the public. The team will apply an advanced atomic layer deposition manufacturing process to achieve self-disinfecting TiO2 coating on Myant's fabric facemasks to enable antibacterial and antiviral properties. This project will deliver low-cost, antibacterial, antiviral, and reusable facemasks to the public, thus helping protect and care for those most at risk in our society. Moreover, this self-disinfecting TiO2 coating can also be used on other personal protective equipment, such as face shields, goggles, and gowns, for frontline healthcare providers.

在COVID-19大流行期间，过滤式面罩净化器（FFR）在保护人们免受潜在的有害空气污染物（如冠状病毒和细菌）的影响方面发挥着不可或缺的作用。然而，大多数FFP是一次性使用的，使用时间为8小时或更短，并且由于污染而必须在使用后进行处置，从而导致公众的FFR严重短缺，并对环境造成破坏性损害。为了应对这些挑战，不列颠哥伦比亚省大学的刘健博士的团队与多伦多的Myant公司合作，旨在开发适合公众日常使用的自我修饰和可重复使用的消费级口罩。该团队将采用先进的原子层沉积制造工艺，在Myant的织物口罩上实现自消毒TiO 2涂层，以实现抗菌和抗病毒性能。该项目将向公众提供低成本，抗菌，抗病毒和可重复使用的口罩，从而帮助保护和照顾我们社会中最危险的人。此外，这种自消毒TiO 2涂层也可用于其他个人防护设备，如面罩，护目镜和长袍，供一线医疗保健提供者使用。
