Quantitative evaluation of antibacterial activities of nanoparticles (ZnO,TiO2, ZnO/TiO2, SnO2, CuO,ZrO2, and AgNO3) incorporated into polyvinyl butyral nanofibers

Novel hybrid polyvinyl butyral nanofibers have been developed for antimicrobial applications. The nanofiber mats were obtained from a needleless rod electrospinning system. The novel inorganic antibacterial agents were incorporated into the nanofibers, and their antibacterial activity was compared. The obtained nanoparticle/nanofiber hybrid mats have a good surface morphology. The results indicated that the CuO, ZnO, ZnO/TiO₂, and AgNO₃ nanoparticle‐incorporated nanofiber layers have excellent antibacterial activity against to Escherichia coli compared with TiO₂, SnO₂, and ZrO₂ ones.
