Abstract
- This paper introduces a multifunctional air filter with a strong ability to trap and disinfect pathogens and absorb particulate matter (PM), the volatile organic compound (VOC), and CO 2. This study demonstrates a facile and eco-friendly synthesis of copper coordination polymer particle (Cu-CPP)-decorated non-woven fibre filters (Cu-CPP/NWF) via an in situ growth dip-coating method. Their multifunction potentials in air pollution treatment are also assessed. The Cu-CPP/NWF filter media showed a remarkable performance for air treatment, with 100% disinfection efficiency against airborne E. coli bacteria (2 × 106 CFU mL−1) in 45 min, superior PM removal efficiency (quality factor 0.299 Pa−1), excellent p-xylene adsorption capacities (1.19 mmol/g) and high potential CO 2 uptake capacities (19.81 cm3/g). A Cu-CPP can work as an antibacterial agent and an adsorbent component, thus offering many applications. The rational integration of Cu-CPP can substantially enhance the filtration efficiency via electrostatic interaction, while most commercial air purifiers rely on dense fibrous filters. This study provides valuable insight into developing a multifunctional and reusable air filter proven to be a life-saving product for public health protection.
