Pristine films of polyvinyl alcohol (PVA)/polyvinyl pyrrolidone (PVP) polymer blend filled with gradient contents (MWCNTs) multi-walled carbon nanotubes have been prepared using ordinary casting technique. Fourier transform infrared (FT-IR) revealed the existence main characteristic peaks corresponding to vibrational groups that characterized synthesized samples. The interaction between nano-composite components was indicated by variation bands in spectral range 1500–1750 cm−1. X-ray...
Casting technique was used for preparation of polyethylene oxide (PEO)/polyvinyl pyrrolidone (PVP) (70/30 wt.%) films filled with different concentrations gold nanoparticles (Au NPs). X-ray diffraction (XRD) pattern proved the semi-crystalline nature pristine and polymer blend. Fourier transform infrared (FT-IR) Ultraviolet/Visible (UV/Vis.) analyses were to retrace structural optical changes increasing Au content. UV/Vis. analysis spectroscopy utilized calculate properties such as energy...
Films of polyethylene oxide and sodium alginate polymer blend (50/50 wt%) embedded with different quantities Au nanoparticles size 3–32 nm were made using the casting process.
Abstract In this work, zinc oxide (ZnO) was produced using extracts of Thymus (Z), Hibiscus rosa-sinensis (K), and Daucus carota (G). Furthermore, sodium carboxymethyl cellulose (CMC) polyvinyl alcohol (PVA) were combined with ZnO to form three novel nanocomposites. X-ray diffraction (XRD) used for the structural analysis, where semicrystalline nature (CMC/PVA)/ZnO nanocomposites confirmed. The characteristics functional groups that arose inside prepared samples identified by Fourier...
Nanocomposite films of polyvinyl chloride/polymethyl methacrylate (PVC/PMMA)/ lithium titanium oxide (Li4Ti5O12) were prepared through a casting method. The structural features the investigated using XRD, TEM, FTIR, SEM, and UV/Vis. spectroscopy techniques. XRD pattern reveals formation crystalline phase average crystallite size 40 nm embedded in amorphous polymeric matrix. observed from TEM images is good agreement with results. physical interaction between PVC/PMMA blend Li4Ti5O12 NPs was...
A blend of polyethylene oxide (PEO)/polyvinyl alcohol (PVA) filled with gradient concentrations selenium nanoparticles (SeNPs) was prepared using a conventional casting technique. The influence content variation on structural, optical, and surface characteristics the studied nanocomposite films evaluated. Characterization studies have shown that ensures uniform controlled distribution SeNPs within polymer network. Infrared spectral data exhibited changes in intensities position...
Abstract Thin polymeric films of poly(vinylidene fluoride) (PVDF) containing variable mass fractions nanoparticles (LiZnVO 4 ) were successfully synthesized via the ordinary solution casting method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR), and ultraviolet–visible spectroscopy used to explore role LiZnVO on structural optical characteristics nanocomposites. In addition, dielectric permittivity (ε' ε") modulus (M' M") investigated. The XRD spectral data reveals crystalline...
