“…Among these, particulate matter (PM) derived from smog, transportation, construction dust, fossil combustion, and emissions are considered major threats that can easily penetrate human organs, causing headaches, cancers, and even death [3][4][5][6]. Escherichia coli, a water-borne pathogenic bacterium, is one of the most common pathogens recognized worldwide, posing a severe risk to human health, especially in underdeveloped and developing countries [7][8][9][10][11][12]. Thus, it is necessary to find effective and practical solutions to prevent the intrusion of PMs and E. coli into the human body.…”

Air pollution and infectious diseases (such as the COVID-19 pandemic) have attracted considerable attention from governments and scientists worldwide to find the best solutions to address these issues. In this study, a new simultaneous antibacterial and particulate matter (PM) filtering Ag/graphene-integrated non-woven polypropylene textile was fabricated by simply immersing the textile into a Ag/graphene-containing solution. The Ag/graphene nanocomposite was prepared by reducing Ag ions on the surface of graphene nanoplatelets (GNPs) using the leaf extract. The prepared Ag/graphene textile was characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Energy Dispersive X-ray (EDX), and contact angle measurements. The results showed excellent integration of the Ag/GNP nanocomposite into the non-woven polypropylene textile matrix. The prepared textile exhibited superhydrophobicity with a contact angle of 152°. The maximum PM removal percentage of the Ag/GNP-integrated textile was determined to be 98.5% at an Ag/GNP content of 1.5% w/w and a silicon adhesive of 1% w/w. The Ag/GNP textile exhibited high antibacterial activity toward Escherichia coli with no sign of bacteria on the surface. Remarkably, the as-prepared Ag/GNP textile was highly durable and stable and could be reused many times after washing. Graphical Abstract
