Characterization and antibacterial activity of rice grain-shaped ZnS nanoparticles immobilized inside the polymer electrospun nanofibers
Advanced Composites and Hybrid Materials(2020)
摘要
Present work introduces the fabrication of antibacterial nanofibers composite of poly(vinyl acetate) doped with in situ-synthesized rice grain-shaped ZnS nanoparticles using electrospinning technique. FE-SEM and TEM analyses revealed that the ZnS nanoparticles were uniformly incorporated inside the polymer nanofibers. The antibacterial activity of as-fabricated nanofibers composite was investigated under indoor light activation towards Gram-negative ( E. coli ) and Gram-positive ( S. aureus ) bacteria. Such strategy for immobilizing ceramic nanoparticles inside polymer nanofibers might be helpful to overcome the photocorrosion and recovery problems of ZnS-based materials. Graphical abstract Fabrication of antibacterial composite nanofibers of rice grain-shaped ZnS nanoparticles and PVAc using versatile electrospinning technique.
