Among other environmental issues, air pollution has become an increasing concern. Notably, particulate matter (PM) with a diameter of less than 2.5 micrometers (PM2.5) poses a serious risk to both the environment and public health, necessitating the development of effective, user-friendly, and adaptable prevention and treatment tools. In this study, we introduce a new reusable air filter that can be easily cleaned and captures PM2.5 with significant efficiency. A highly stable network of silver nanowires covered by sheets of graphene oxide were sequentially deposited on nylon fabric by dip coating, followed by 15 min of annealing at 120 °C. The fabricated filter not only removes PM2.5 with high efficiency (greater than 98.7%) but also demonstrates stable reusability. Moreover, the silver nanowires have long-term stability because the graphene oxide layer prevents oxidization in the air. Overall, this research demonstrates the potential of high-performance PM capture devices using simple materials and production methods.
