Preparation, Properties, and Microbial Impact of Tungsten (VI) Oxide and Zinc (II) Oxide Nanoparticles Enriched Polyethylene Sebacate Nanocomposites

Abstract

Nanoparticles of tungsten oxide (WO3) and zinc oxide (ZnO) enriched polyethylene sebacate (PES) nanocomposites were prepared through the coprecipitation process and condensation polymerization reaction. The obtained nano-sized particles of WO3 and ZnO, PES, and nanocomposites (WO3-PES NC and ZnO-PES NC) were investigated. The average molecular weight of the cured PES was measured by employing the gel permeation chromatography (GPC) technique. Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) spectra assured the formation of the polymeric nanocomposites.WO3 and ZnO nanoparticles supposed a condensed porous spherical phase found implanted in the polymer structure, as detected by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) methods. These nano-scale systems achieved an electrical activity based on the conductive nanoparticles embedded matrix as a result of the ion–ion interactions. The microbial influence of the nanocomposites was examined against pathogenic bacteria; Pseudomonas aeruginosa,Escherichia Coli, Staphylococcus Aureus, and Bacillus subtilis, and Fungi; Aspergillus niger, and Candidaalbicans. Results exhibited that these nanocomposites have antimicrobial effects from moderate to slightly high on bacteria and high on fungi which was confirmed by a clear zone of inhibition. This study contributes to the design of reasonable composites to be under evaluation for their catalytic effect.

Hydroxyapatite Decorated with Tungsten Oxide Nanoparticles: New Composite Materials against Bacterial Growth

“…This result can be ascribed to the lower permeability of E. coli compared to the tested S. aureus , due to the presence of the outer membrane and lipopolysaccharides in the Gram-negative bacterial cells [ 27 , 28 ]. The highest antibacterial activity of WO 3 nanoparticles against Gram-positive bacteria has been previously reported [ 17 , 29 ].…”

“…[ 136d,137a,d,142 ] Similarly, AgCl is a promising antibacterial material whose antibacterial ability has also been improved by adding WO x which promoted the release of Ag + ions. [ 143 ] Other combinations, such as WO x ‐graphene oxide, [ 144 ] WO 3 ‐ZnO, [ 145 ] and poly( N ‐methylpyrrole)/WO 3 , [ 146 ] also take advantage of the narrow band gap of WO x to increase the optical band gap to achieve a wider antibacterial spectrum. In addition to WO x , WS 2 also possesses significant antibacterial ability.…”

Effective removal of malachite green from local dyeing wastewater using zinc-tungstate based materials

“…This significant increase has been linked to the stacking of B, C and N particles on the surface of the ZnWO 4 nanomaterial, hence the ZnWO 4 @BCN/N has a higher tendency to enhance the adsorption process than the others based on the higher surface area as well as pore size [ 14 ]. The presence of the B, C and N ions on the ZnWO 4 matrix, contributed to the increase in mesoporosity caused by simultaneous displacement and substitution of O 2 in the ZnWO 4 by B 3+ and N 3− , while C 4+ was incorporated into the materials [ 63 ]. The dopant ions led to a wide opening of the pores at high relative pressure and formed heterojunctions in the case of multiple metal-doped [ 64 ].…”
