The coronavirus (COVID-19) pandemic has led to thousands of deaths and significant economic contraction globally. Coronavirus can be transmitted via contact or respiratory droplets emitted during a cough or sneeze, and/or by touching surfaces contaminated with respiratory droplets or secretions. Therefore, demand for "self-disinfecting" coatings which can kill germs and viruses has skyrocketed in recent months. In this project, self-disinfecting coatings will be developed to inactivate viruses rapidly, spontaneously and continuously under visible light illumination. The development of self-disinfecting coatings will be based on graphitic carbon nitride, a low cost, non-toxic and visible light absorbing photocatalyst with good thermal and chemical stability. The success of this project will lead to the application of self-disinfecting coatings on cellulose, key materials for the inner layer of face masks, tempered glass used in windows and metallic surfaces such as those used in door handles. We believe the success of the project will help minimize the spread of COVID-19 as well as help Canadian companies develop products that can be marketed as self-disinfecting coatings.

新型冠状病毒（COVID-19）大流行已导致全球数千人死亡及严重经济萎缩。冠状病毒可以通过接触或咳嗽或打喷嚏时散发的呼吸道飞沫传播，和/或通过触摸被呼吸道飞沫或分泌物污染的表面传播。因此，近几个月来，对能够杀死细菌和病毒的“自消毒”涂层的需求急剧上升。 本项目将开发自消毒涂料，在可见光照射下快速、自发、连续地杀灭病毒。自消毒涂料的开发将基于石墨碳氮化物，一种低成本、无毒和可见光吸收的光催化剂，具有良好的热稳定性和化学稳定性。该项目的成功将导致自消毒涂层在纤维素、口罩内层的关键材料、窗户用钢化玻璃和门把手等金属表面上的应用。我们相信，该项目的成功将有助于最大限度地减少COVID-19的传播，并帮助加拿大公司开发可作为自消毒涂料销售的产品。
