electrospun chitosan-polyethylene oxide nanocomposite mats containing zif-8 nanoparticles

Antimicrobial chitosan–polyethylene oxide (cs-peo) nanofiber mats loaded with 3, 5 and 10% (w/w) of zeolitic imidazolate framework-8 nanoparticles (zif-8 nps, ~60 nm diameter) were developed by electrospinning technique the cs-peo-ga-3% zif-8 nps crosslinked with glutaraldehyde (ga) vapor was also prepared the sem images indicated that the nanofibers had average diameters within the range ~70–120 nm the crosslinked cs-peo-ga-3% zif-8 nps sample was less thermally stable but more hydrophilic than its related non-crosslinked mat reflecting there was no need to crosslink the fibers using a chemical crosslinker having adverse effects the highest hydrophobicity and appropriate thermal and tensile properties of cs-peo-3% zif-8 nps among those of the mats including 5 and 10% zif-8 nps suggested that the mentioned mat is the most suitable sample for food coating applications
