There is an urgent need to provide personal protection equipment (PPE) to front-line health practitioners and other essential workers during this COVID-19 pandemic. One of the desirable factor would be that the virus is killed readily when in contact with the materials of PPE and other frequently used surfaces. Studies suggest that COVID-19 virus remains viable on surfaces such as cloth (textile materials), metals, plastics, woods, rubber, glass, and papers for different duration ranging anywhere from a few hours to over 24 hrs. Therefore, it is important to device a coating material that would be applied to PPE and other surfaces, which would kill the virus instantaneously and its antiviral efficacy would remain for extended period. The Waterloo research team in collaboration with SiO2 Innovation Labs will work towards this important goal of bringing such functional coatings to the marketplace. This would involve development of techniques to durably coat the antiviral material of different surfaces, understand the origin of the physical forces between virus and the coated materials through careful experiments and computational models and finally come up with an optimal formulation of the coating materials based on these studies. Once successfully achieved, the desired coating material will propel the industry partner in marketing their coating to large number of end-users and would eventually save millions of lives worldwide.

在2019冠状病毒病大流行期间，迫切需要为一线卫生从业人员和其他重要工作人员提供个人防护设备（PPE）。其中一个理想的因素是，当与PPE材料和其他常用表面接触时，病毒容易被杀死。研究表明，COVID-19病毒在布料（纺织材料）、金属、塑料、木材、橡胶、玻璃和纸张等表面上保持活力的时间从几小时到超过24小时不等。因此，重要的是设计一种涂覆材料，该涂覆材料将被施加到PPE和其他表面，其将立即杀死病毒并且其抗病毒功效将保持较长的时间。滑铁卢研究团队与SiO2创新实验室合作，将致力于将这种功能性涂料推向市场的重要目标。这将涉及开发技术来持久地涂覆不同表面的抗病毒材料，通过仔细的实验和计算模型来理解病毒和涂覆材料之间的物理力的起源，并最终基于这些研究提出涂覆材料的最佳配方。一旦成功实现，所需的涂层材料将推动行业合作伙伴将其涂层推向大量最终用户，并最终挽救全球数百万人的生命。
