Fabrication of Multifunctional Nano Gelatin/Zinc Oxide Composite Fibers

Abstract

According to health studies, reinforcing gelatin is necessary in order to obtain the multifunctional material. In this study, nano zinc oxide (ZnO; at concentrations of 0.5%, 1% and 1.5%) was doped with gelatin and the solution was electrospun under specific conditions to obtain multifunctional gelatin/ZnO nanofibers. The morphology of the nanofibers was studied by field emission scanning electron microscope (FESEM), and energy-dispersive X-ray spectrometry (EDX) analysis indicated the presence of nano Zn on the surface of gelatin fibers. On the contrary, elemental mapping analysis proved the distribution of nano material along the nano gelatin fibers. The results show that the produced nano gelatin/ZnO composite increases the ultraviolet (UV) blocking of fabric significantly. It is also observed that electrospun gelatin/ZnO nanofibers have excellent bactericidal property against both Bacillus cereus (Gram-positive) and Escherichia coli (Gram-negative) bacteria.

Antimicrobial Clothing Based on Electrospun Fibers with ZnO Nanoparticles

“…According to health research, reinforcing gelatin is required to obtain the multifunctional substance. In this study, nano zinc oxide (ZnO; concentrations of 0.5%, 1%, and 1.5%) was doped with gelatin and electrospun under certain conditions to produce multifunctional gelatin/ZnO nanofibers [ 101 ].…”

“…In comparison, the antibacterial activity of the sample treated with 1% nano ZnO is approximately 100% and 98.2% for E. coli and Bacillus cereus , respectively, and 97.4% and 96.1% for the sample containing 0.5% nano ZnO. When the antibacterial properties of samples are compared, it is discovered that the antibacterial properties of samples against E. coli are greater than those of Bacillus cereus due to differences in cell wall thicknesses [ 101 ].…”
