| Abstract Scope |
Removal of airborne viruses can lead to an improvement of public health and especially in places such as hospitals. Removal of these infectious particles from contaminated air can be achieved with air filters, which usually trap the particles based on size. However, these filters are costly and accumulation and proliferation of microbes in the filter are associated problems. Here, we designed MXene-based surface coatings that can lead to enhanced biological effects. Uniform MXene-based surfaces were fabricated through spray coating on commercial air filters, with limited increase in the pressure drop during air filtration. Compared to pristine air filters, the MXene-coated ones showed an improved virus removal efficiency from 50~% to ~80%. Close to 100% removal of the viruses was achieved by applying a low voltage (< 2 V) or microwave to the MXene-based surfaces. This is ascribed to the excellent electronic conductivity and electromagnetic wave absorption properties. |
