Effects of poly(ethylene oxide) and ZnO nanoparticles on the morphology, tensile and thermal properties of cellulose acetate nanocomposite fibrous film

A bio-based fibrous film aimed to be used as food-packaging component was electrospun from blend solutions of cellulose acetate (CA) and poly(ethylene oxide) (PEO). CA/PEO blend ratios were varied to unveil the effect of PEO on morphology, moisture-adsorption and tensile properties of the blend fibrous films. The results indicated that the addition of PEO could improve tensile strength, elongation and elasticity of the CA-based fibrous film. Zinc oxide nanoparticles incorporated into the blend fibers were shown to improve tensile and thermal properties of the nanocomposite film.
