ABSTRACT
Face masks are effective response to address this havoc pandemic caused by respiratory infection virus, but they are lack of reusable, antibacterial, and antiviral abilities due to their simple filtration mechanism, bringing to a supply shortage and severe plastic pollution globally. Herein, we designed reusable, antiviral, and antibacterial masks (referred to as R2A masks) that transformed from commonly-used standard masks and household fabrics based on the polyphenol-based surface functionalization. R2A nanocoatings are mainly composed of supramolecular complexation of natural polyphenols and metal ions, possessing a high performance of antibacterial property and comprehensive recyclability. Interfacial interaction of R2A nanocoating can effectively capture the spreading of particulate matters and aerosols containing virus-mimic nanoparticles even after 10 recycles. Moreover, R2A masks exist antibacteria and antivirus for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Collectively, this simple functional enhancement of masks provides a sustainable and strategic preparation for combating the infectious respiratory diseases.
