Photocatalytic coatings for microbial disinfection

2019冠状病毒病凸显了公众对高交通量地区高接触表面微生物传播的担忧。 在交通、教室和电影院等人员流动率高的地方，企业进行清洁和消毒，以防止疾病传播，使人们能够舒适地恢复正常生活。 典型的消毒剂，如漂白剂和过氧化氢，对杀灭微生物是有效的，但只有在清洁过程中与微生物接触时才有效。本项目的目标是通过长时间保持活性的涂层来实现连续的被动消毒，从而使沉积在涂层表面上的微生物失活。 与麦克雷Imaging的合作伙伴关系是关于开发一种与织物兼容的涂层，以及部署在座椅罩上的类似柔软和灵活的表面。 涂层的消毒能力是基于水的。 光催化剂通过在光的存在下破坏有机键来工作。

COVID-19 has highlighted public concern with microbial transmission in high traffic areas with high-touch surfaces. In places like transit, classrooms and movie theatres where there is a high turnover of occupants, businesses clean and disinfect to prevent spread of disease so that people can be feel comfortable in resuming their normal lives. Typical disinfectants, like bleach and peroxide, are effective at killing microbes, but only while they are in contact, during the cleaning process.The goal of this project is to create continuous passive disinfection with a coating that remains active over a long period of time, so that microbes that are deposited on coated surfaces can be deactivated. The partnership with McRae Imaging is about developing a coating that is compatible with fabrics, as well as similar soft and flexible surfaces, that are deployed on seating covers. The disinfecting ability of the coating is based on photocatalysis. Photocatalysts work by breaking organic bonds in the presence of light.
