Surface Modified

Abstract Surface modification of Zinc oxide nanoparticles (ZnO) with γ-aminopropyltriethoxy silane (APTES) was investigated. Successful surface modification of the nanoparticles was confirmed experimentally by X-ray Photoelectron Spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR). The effect of the surface modifier concentration on the grafting density and surface area was studied by CHN elemental analysis and Brunauer–Emmett–Teller (BET) analysis. The photocatalytic activity and UV shielding ability of the surface-modified particles prepared in water-ethanol solvent in the presence of the surface modifiers were compared to those of non-modified particles. As a case study, It was observed by methylene blue (MB) dye degradation experiment that the photocatalytic activity in the presence of modified nanoparticles was lower than that observed with non-modified ZnO nanoparticles. Dispersion stability tests visually showed that APTES grafted nanoparticles had acquired better stability than non-modified ZnO nanoparticles in aqueous solution.

Major Threat

Development of antimicrobial nanomaterials is one of the most attractive strategies for eliminating the major threat of pathogenic bacteria to public health. In this work, we developed a simple impregnation-reduction method for the synthesis of Ag-doped hierarchical ZIF-8 (Ag/H-ZIF-8) nanocomposite. The nanocomposite was characterized by several techniques and its antibacterial activity was investigated. The Ag nanoparticles are uniformly dispersed in the porous ZIF-8 with narrow size distribution. Consequently, the resulting Ag/H-ZIF-8 nanocomposite showed significantly enhanced antibacterial activities compared to the single ZIF-8 or Ag nanoparticles. Furthermore, the composite is biocompatible, because no obvious toxicity was observed on Hepatic epithelial cells. This study offers a new approach for the design of hybrid antimicrobial nanomaterials that have great potentials in practical disinfections

Uv Protective Properties

A novel ZnO nanoparticles aqueous solution was prepared through a one-step reaction between a modified hyperbranched polymer-PNP and zinc nitrate. During the reaction process, PNP not only acted as the reagent to produce ZnO nanoparticles, but also controlled the size of the synthesized ZnO nanoparticles and stabilize them after reaction. The size of ZnO nanoparticles were about 6 nm with narrow size distribution. Then the ZnO nanoparticles were utilized for the functional finishing of cotton fabrics by in situ generation and deposition method. Scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX) and X-ray diffraction (XRD) measurements confirmed the ZnO nanoparticles coated on the cotton fibers. The treated cotton fabrics exhibited excellent UV protective properties and antibacterial activities. When the ZnO content in cotton fabric was 2.23 %, the UPF value of treated cotton fabric reached 114.4 and the bacterial reduction rates againstStaphylococcus aureus(S. aureus) andEscherichia coli(E. coli) both exceeded 98 %.
