antibacterial chitosan/polyethylene oxide nanofibrous mats

The zif-8 nanoparticles were synthesized and applied for the fabrication of electrospun cs-peo nanofibrous mats containing three different weight percents (3, 5 and 10%) of zif-8 nps the cs-peo-ga-3% zif-8 nps crosslinked with glutaraldehyde (ga) vapor was also prepared in order to examine its properties and compare the results with those of non-crosslinked sample according to the fe-sem images, the spherical zif-8 nps were ~60 nm in size and all of the nanofibers had average diameters of ~70–100 nm water contact angle test illustrated that the hydrophobicity of the cs-peo-3% zif-8 nps mat was the highest among other mats surprisingly, the cs-peo-3% zif-8 mat exhibited 100% antibacterial activity against both the gram-positive staphylococcus aureus and gram-negative escherchial coli bacteria finally, the cs-peo-3% zif-8 nps mat was considered as the most preferred sample for food coating/packaging applications due to its highest hydrophobicity as well as appropriate thermal and tensile properties
