项目摘要

The current pandemic has highlighted the importance of personal protective equipment (PPE) for frontline workers to protect both them and the public from transmitting the virus. Most of this PPE is made of clear plastic (face shields, dividers, windows, etc.) which prevent direct person-to-person transmission via aerosolized fluid droplets via coughs, sneezes, etc. However, they do not protect against infection by indirect contact (e.g., touching a contaminated mask with bare hands or gloves then touching your eye). Furthermore, many other surfaces may also act as hotspots for indirect contact transmission. To avoid these indirect exposure routes, researchers at the University of Waterloo in collaboration with Evercloak Inc. propose to develop a transparent coating which can be applied to PPE and other high risk surfaces and is capable of killing SARS-CoV-2 and other microbes. The films act continuously during use when illuminated with ambient, indoor light. While the concept of self-cleaning windows has been widely commercialized, such coatings only work under direct sunlight due to the requirement of UV activation. The coatings developed in this collaboration based on ultra-thin 2D material semiconductors will, instead, operate under indoor light conditions (no UV required) and enable self-cleaning surfaces in an indoor environment such as a hospital or grocery store. Beyond the COVID-19 crisis, such coatings can also be used to decontaminate other commercial products like touch screens of phones, tablets and kiosks and should significantly reduce the risk of disease transmission.

目前的大流行强调了个人防护设备（PPE）对于一线工人和公众免于传播病毒的重要性。此PPE的大部分是由透明的塑料（面罩，隔板，窗户等）制成的，可防止通过咳嗽，打sneezes等通过气溶液液滴进行直接的人对方传播。但是，它们不会通过间接接触来防止感染（例如，用裸手或触摸裸手或触摸您的眼睛触摸受污染的蒙面，然后触摸您的眼睛）。此外，许多其他表面也可以充当间接接触传输的热点。为了避免这些间接的暴露路线，滑铁卢大学与Evercloak Inc.合作开发透明涂层，该涂层可以应用于PPE和其他高风险表面，并能够杀死SARS-COV-2和其他微生物。当用环境，室内光照亮时，电影在使用过程中不断起作用。虽然自我清洁窗户的概念已被广泛商业化，但由于紫外线激活的要求，这种涂层仅在阳光直射下起作用。相反，基于超薄2D材料半导体的涂层将在室内光条件下（无需紫外线）运行，并在室内环境中启用自我清洁的表面，例如医院或杂货店。除了19危机之外，此类涂料还可以用于净化其他商业产品，例如手机，平板电脑和售货亭的触摸屏，并应大大降低传播疾病的风险。
