Superhydrophobic, Antibacterial Air Filter via One-Step Coating Method |
| 초록 |
The spread of emerging infectious diseases via bioaerosols (airbone microrganisms), such as the COVID-19 pandemic, made it essentional to wear personal protective equipment such as a mask. The mask filter can capture bio-aerosols to prevent infiltration of the respiratory tract, but the attached microorganisms can multiply surrounding moisture and dust as nutrients and cause secondary infection. To overcome this issue, antibacterial activity that kills microorganisms on the filter surface is an essential property. We report a antibacterial mask filter with effectively produce visible light triggered biocidal ROS. In particular, dip-coated filter with rose bengal, a photosensitizer dye for ROS generation and hydrophobic octadecylamine binding to Si-Al sol together was realized superhydrophibicity by roughly formed filter surface into a flower-like structure. The biocidal properties of the coated filter were demonstrated by ROS production measurements and antibacterial performance. |
