Özet:

 

Zinc oxide/sodium cellulose composite with different ZnO   loadings was prepared for the first time. The crystal structures of   cellulose, sodium cellulose, and ZnO/sodium cellulose composite were   characterized by FT-IR, XRD, XPS, SEM, and EDX. ZnO/sodium cellulose showed   a similar XRD pattern to that of cellulose II. The XPS spectrum emphasized   the presence of Zn2+2+^{2+} and Na++^{+\, } ions in the prepared composite.   Additionally, the SEM analysis showed the growth of ZnO crystals on the   sodium cellulose surface. UV-Vis spectrometry of the ZnO/sodium cellulose   spectrum showed a distinguished absorption band at 360 nm that was   attributed to the presence of ZnO particles on the cellulosic fibers. As a   result, the composite fibers swelled, and their diameter increased from 15   \textmu m to 30 \textmu m. Furthermore, ZnO/sodium cellulose exhibited lower   air and water vapor permeability than cellulose and sodium cellulose and can   be perfectly utilized as food packing film to increase the shelf life of   preserved foods.
