Abstract

The aim of the present study is to fabricate neat nanofibers and hybrid ones containing metal-organic frameworks (MOF) and assess and compare their performance to remove of bioaerosols from air stream. Moreover, the antibacterial properties of neat and hybrid nanofibers have been investigated. According to the findings, both neat and hybrid media had better mean microorganism collection efficiency at face velocity of 0.1 m/s compared to 0.3 m/s (p>0.05). The studied media were better able to remove Staphylococcus aureus than Escherichia (p>0.05). Increased temperature had no significant effect on the filtration efficiency (p>0.05). Increased relative humidity lead to significant reduction in the removal efficiency of Escherichia for hybrid media (p<0.01). Results show that both neat and hybrid media have antibacterial properties, though this is weaker in the neat nanofibers compared to the hybrid one. The use of nanofibers containing MOF can considerably increase the microorganism collection efficiency of nanofibers and its antibacterial properties. © 2021, The Korean Fiber Society for Fibers and Polymers and Springer.
