摘要

As the world grapples with the daunting challenge of air pollution, which claims millions of lives annually and continues to deteriorate air quality, especially in urban areas, the quest for innovative air filtration solutions has become more pressing than ever. The present study explored the fabrication of non-woven electro-spun PTFE-NiO composite nanofiber filter mats. The fabricated filter mats showed a high-water contact angle of 120.55 ± 2.20 degrees, high hydrophobicity values, high porosity (87%), maximum pore size (1.00 μm), low surface energy (1.46–3.70 mN/m) values that further enhanced the filtration efficiency, self-cleaning property and durability of nanofiber filter mats for practical applications. Results of the filtration capability of heat-treated PTFE-NiO 6 wt% nanofiber filter mats showed a maximum efficiency range from 97.49% to 99.33% for both PM2.5 and PM10. PTFE-NiO 6wt% showed a good quality factor as compared with the commercial PTFE filters, 0.0245(Pa−1). The pressure drop of the synthesized filter was also low (50 Pa) compared to the commercial filters (62 Pa). The multifunctionality of air filters was further supported by the findings of the antibacterial and self-cleaning tests, which also showed that filter mats had high self-cleaning properties and inhibited bacterial growth on the filter surface. Our study demonstrates nanofibrous mats’ enormous practical application potential, especially in reducing pollution and related health hazards in hospitals and educational facilities.
