Abstract:

Wearing masks has been widely recommended as a way to prevent respiratory diseases amid the normalization of the COVID-19 pandemic. There is a demand for masks that goes beyond simply being filters for aerosols containing microbes, and it can fulfill more needs such as antimicrobial, antiviral, self-cleaning and detection. Masks with antibacterial and antiviral functions can effectively kill pathogens trapped in the filter layer of masks and reduce sources of pollution and infection. Masks with self-cleaning function can realize the recycling of masks, alleviate environmental pollution and resource waste. Masks with self-detection function can realize instant visual detection of pathogens and solve the discomfort caused by routine sampling. Various functional modifications improve the mask's performance, such as metal nanoparticles and herbal extracts to inactivate pathogens. Carbon-based nanoparticles make masks photothermal and superhydrophobic to prolong the life of masks. Metal nanoparticles can be used for pathogen detection by quenching or enhancing their fluorescence. This paper reviews the recent progress in the development and functionalization of functional masks with the advancement of material science in the last three years and the development direction of multifunctional masks is forecasted.
