Abstract: (2107 Views)
Background and Objective: The accumulation of airborne bioaerosols on filtration media and their gradual proliferation in the presence of appropriate moisture and environmental conditions is one of the major problems against using these media. The use of hybrid media containing antibacterial agents is one of the available solutions to this problem. The present study aimed to fabricate nonwoven nanofiber media with an antibacterial activity using an electrospinning process.
Materials and Methods: Polyurethane-chitosan nanofiber media the weight ratios of 100 to 0, 90 to 10, 80 to 20, and 70 to 30 were fabricated by simultaneous electrospinning process. The evaluation of the antibacterial properties of the media was performed after their preparation by standard methods of disk diffusion (ISO 20645) and colony counting (ISO 20743).
Results: The investigation of antibacterial activity of samples by both methods showed that the media with polyurethane to chitosan weight ratio of 70 to 30 had suitable antibacterial activity. The mean values of bacterial growth inhibition zone and antibacterial activity for polyurethane-chitosan (70/30) media were obtained at 0.26 and 2.225 mm, respectively, indicating the significant antibacterial activity of this media.
Conclusion: The results showed that antibacterial nanofiber media can be created by adding chitosan nanofibers as antimicrobial agents to the polyurethane nanofiber.
