In this study, cupric oxide (CuO) nanoparticles were synthesized via sonochemical method. The samples were characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope, and transmission electron microscopy. The spherical CuO nanoparticles were dispersed in sodium hexametaphosphate under sonication (25 kHz) to analyze the particle size distribution and UV absorption spectra. Using these absorption spectra, we further examined the CuO nanoparticle to explore the possibility of using them as a material for applications such as solar cell and textile production.
Magnesia (MgO) nanoparticles were produced from magnesite ore (MgCO3) using ball mill. The crystalline size, morphology and specific SSA were characterized by X-ray diffraction analysis, transmission electron microscopy and Brunauer-Emmett-Teller method, respectively. MgO nanoparticle-incorporated nylon 6 solutions were electrospun to produce nanofiber mats. Surface morphology and internal structure of the prepared hybrid nanofiber mats were examined by scanning electron microscopy and high-resolution transmission electron microscopy, respectively. The fire retardancy and antibacterial activity (Staphylococcus aureus and Escherichia coli) of coated fabrics made from MgO/nylon 6 hybrid nanofiber are better than those from nylon 6 nanofiber.
In this investigation, various metal
oxide (ZrO2, MgO, TiO2) nanoparticles were prepared
using the hot-air spray pyrolysis method. The prepared nanoparticles
were characterized using the X-ray diffraction (XRD) technique, scanning
electron microscopy (SEM), and transmission electron microscopy. The
colloidal silica (SiO2) sol was prepared using the sol–gel
method, mixed with various metal oxides (ZrO2, MgO, TiO2). Uncoated cotton fabrics were separately impregnated with
the prepared nano(composite) sols followed by the pad-dry-cure method.
The structural analysis of the coated and uncoated fabrics was performed
using XRD. The surface morphology of the coated and uncoated cotton
fabrics was analyzed using SEM. The elemental analysis using energy-dispersive
spectroscopy confirmed the presence of nanoparticles along with cellulose
on the surface of the fabric. The thermal stability and flame retardancy
properties and residue of the coated and uncoated fabrics were studied.
The coated cotton fabrics showed better antibacterial activity against Staphylococcus aureus and Escherichia coli. The biocompatibility performance of the coated fabrics was in the
order TiO2/SiO2 > MgO/SiO2 >
SiO2 > ZrO2/SiO2.
