Experimental analysis indicates significant antibacterial performance in plasma-treated PP nonwoven fabric against Escherichia coli and Staphylococcus aureus, implying potential applications in medical textiles.
In this work, polypropylene (PP) melt-blown nonwoven fabric was used as a raw material, which was plasma-treated and grafted with HBP/Ag nanoparticle (NP) solution. The surface wettability, surface morphology, and surface element composition after the treatment were evaluated through a contact angle test, field emission scanning electron microscopy (FE-SEM), energy-dispersive spectrometer (EDS), and Fourier transform infrared spectroscopy (FTIR), respectively. The antibacterial activity of PP fabrics treated with Ag NPs against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) was measured. SEM and EDS results showed that Ag NPs were evenly dispersed on the surface of the PP fabrics. The PP fabrics treated with Ag NPs exhibited excellent antibacterial performance.
