Sustainable solutions on fabricating and using a face mask to block the SARS-CoV-2 spread during this COVID-19 pandemic are required as society is directed by WHO towards wearing it, resulting in an increasingly huge demand with over 40,000,000,000 masks used per day globally. Herein, we review various new mask technologies and advanced materials to deal with critical shortages, cross-infection and secondary transmission risk of masks. A number of countries have used cloth masks and 3D-printed masks as substitutes, whose filtration efficiencies can be improved by using nanofibers or mixing other polymers into them. Since 2020, researchers continue to improve the performance of masks by adding various functionalities, for example using metal nanoparticles and herbal extracts to inactivate pathogens, using graphene to make masks photothermal and superhydrophobic, and using TENG to prolong mask lifetime. The recent advances in material technology have led to the development of antimicrobial coatings are introduced in this review. When incorporated into masks, these advanced materials and technologies can aid in the prevention of secondary transmission of the virus.
