Abstract Polyvinylidene fluoride and polymethylmethacrylate (PVDF/PMMA) films were blended with different concentrations by casting method. Structural, spectroscopic, morphological characteristics of both the interface surface have been investigated. The blends characterized using X‐ray diffraction (XRD), Fourier transform infrared (FTIR), UV–visible, differential thermal analysis (DTA), scanning electron microscopy (SEM). All measurements reveal that take place based on influence PMMA...
In this work, FT-IR, Raman, TEM spectroscopy and AC conductivity were used to study characterize of PEO/PVDF blend incorporated with low content multi-walled carbon nanotubes (MWCNTs). Main characteristics IR Raman bands for the two polymers MWCNTs observed. The shift G, D G″ occurred. All results showed that MWNTs-COOH covalently linked through OH C–C bonds. images illustrated MWNTs well dispersed into polymeric matrices wrapped chains. temperature dependent measurements nanocomposites...
Composite films of polyvinyl alcohol (PVA)/Silver nanoparticles (AgNPs) were synthesized via casting method. The presence AgNPs in PVA was approved by an apparition Surface Plasmon Resonance (SPR) around 427 nm the composite absorption spectra. nanocomposite irradiated at different times (5, 10, and 15 min) pulsed Nd:YAG laser. integral intensity diffracted X-ray photons from has been increased noticeably after doping process denotes increasing ordering character PVA/Ag to time's laser,...
The effective role of Lithium Titanate (Li4Ti5O12) filled in Poly (vinylidene fluoride)/Poly (n-vinyl carbazole) (PVDF/PVK) (80/20 wt/wt%) blend matrix was demonstrated. PVDF/PVK/Li4Ti5O12 nanocomposite films with ratios 0.2, 0.5, 1.5, and 2.0 wt% Li4Ti5O12 NPs have been successfully synthesized via casting technique. Structural, optical, electrical properties the prepared evaluated several techniques such as; XRD, FTIR-ATR, UV–vis A.C. conductivity. XRD FTIR-ATR results confirmed...
Carboxymethyl cellulose/polyacrylamide (CMC/PAM) blend was used as a matrix material for fabricating nanocomposite samples reinforced with the cubic lithium titanate nanoparticles (Li4Ti5O12 NPs, particle size <55 nm) by solution casting method. The structural, optical, thermal, mechanical, and dielectric properties of were investigated. CMC/PAM structure's increased amorphous areas existence hydrogen coordination bonds in both revealed XRD FT-IR spectra. optical measurements indicated...
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...
Novel nanocomposites based on PVDF/PVC blend containing graphene oxide nanoparticles (GO) were prepare using sonicator. IR analysis revealed that the addition of GO prompts a crystal transformation α-phase PVDF. The change structural before and after adding to studied by X-ray diffraction. A decrease in activation energy gap from UV data was observed with increasing content, implying variation reactivity as result reaction extent. ε′ frequency is nearly same ε″. At higher frequencies, both...
Structural, thermal, and mechanical properties of pure blend nanocomposites based on polyurethane (PU) polyvinyl chloride (PVC) doped with low different content single walled-carbon nanotubes (SWCNTs) were studied. The at concentration prepared via casting technique. interaction between PU/PVC CNTs examined FT-IR studies. changes in the structures using X- Ray Diffraction (XRD), results indicated that amorphous domains increased increasing SWCNTs content. Transmission electron microscope...
Abstract Pure nickel ferrite nanoparticles (NiFe 2 O 4 NPs) were prepared by the solvothermal method. Different concentrations of NiFe added to PVDF/PEO blend prepare PVDF/PEO-NiFe nanocomposite films. The films characterized using different techniques in detail. NPs images have a semispherical shape and roundness edges, with average particle size ~ 4.3–8.8 nm, polycrystalline structure. show that micrometrical agglomeration suggests presence pore-free crystallites on surface. spectroscopic...
Abstract Using the solution casting method, a blend of polyvinyl alcohol/chitosan (PVA/Cs) was prepared with different amounts polypyrrole (PPy) to enhance structural and electrical conductivity films. The miscibility interaction between PVA/Cs were confirmed by FT-IR measurements shifting disappearing some bands suggesting that PVA functional group interacted every other on Cs side chain. For PVA/Cs/PPy, band intensities varied, indicating PPy PVA/Cs. XRD showed addition leads noticeable...
Abstract Gold nanoparticles (AuNPs) were synthesized via laser ablation technique. PEO/CMC-AuNPs nanocomposites prepared using the casting method. Water was chosen as a solvent because it considered an eco-friendly compared to other organic solvents. SEM micrographs reveal uniformly distributed AuNPs on sample surface. 3D images used estimate roughness parameters.
