Abstract and Figures

Erythrosine B/PVA polymeric composite films were prepared with different concentrations of Erythrosine B (EB) as 0, 1, 2, and 4 wt% of EB utilizing the casting procedure. The crystal structure of Erythrosine B /PVA films was identified by X-ray diffraction patterns (XRD). The frequency (100 Hz − 1 MHz) reliance on both dielectric constant (ε1) and dielectric loss (ε2) was investigated. Both ε1 and ε2 of Erythrosine B/PVA polymeric composite films decreased with increasing frequency and increased by rising percent EB wt%. The ac conductivity of Erythrosine B/PVA films showed increased behavior by raising frequency. Moreover, the frequency exponent (s) decreased slightly from 0.99 to 0.96 with increasing concentrations. The increase in Erythrosine B content enhances the values of  σ ac\:{{\sigma\:}}_{\text{a}\text{c}} for EB/PVA polymeric composite films. The density of states N(Ef) is calculated at specific frequencies for different concentrations of EB for Erythrosine B /PVA polymeric composite films, and it has values in the order of 10¹⁸ cm− 3 eV− 1.

  • May 2025
The current work utilized the casting techniques to manufacture a polyvinyl alcohol (PVA)/polyvinylpyrrolidone (PVP)/ polyethylene glycol (PEG) blend filled with nano ZnO/Co for uses in energy storage and radiation shielding. The subsequence of doping amount of ZnO/Co on the structural and morphological features of the host matrix was explored. Blend with 3 wt% ZnO/Co has the greatest dielectric constant and a c conductivity. The influence of filling percentage on the electric modulus and relaxation time of the host blended polymer was analyzed. All blended polymers’ relaxation mechanisms are shown by the non-Debye model. Doped polymers exhibited higher capacitance relative to the pure blend. The incorporation of ZnO/Co results in an elevation of the linear attenuation coefficient (LAC) and a marginal mass-attenuation coefficient (MAC) rise. The addition of varying quantities of nano ZnO/Co to the host blend led to half value layer (HVL) and tenth-value-layer (TVL) reduction. A doped blend with 5 wt% ZnO/Co is the most beneficial for shielding applications. 5 wt% ZnO/Co doped blend demonstrated the maximum fast neutron removal cross-section (FNRCS) value (0.136 cm⁻¹) among all blends. At 0.1 MeV, energy absorption buildup factor (EABF) values at 40 mean-free-path (MFP) revealed a peak for the undoped blend (54987.68), ZnO/Co (1%) (45862.67), ZnO/Co (3 wt%) (38354.31), and ZnO/Co (5 wt%) (32535.23). The exposure buildup factor (EBF)-values demonstrate a peak at 0.1 MeV for the undoped blend (93991.58), ZnO/Co (1 wt%) (70910.70), ZnO/Co (3%) (52842.13), and ZnO/Co (5 wt%) (40308.90) at 40 MFP.

The two compounds (E)-3-((5-hydroxy-3-methyl-1-((methylthio)carbonothioyl)-1H-pyrazol-4-yl)diazenyl) pyridin-1-ium 4-methylbenzenesulfonate (PPC) and (E)-methyl 5-hydroxy-3-methyl-4-(naphthalen-1-yldiazenyl)-1H-pyrazole-1-carbodithioate (NPC) compounds are chemically synthesized. Their chemical structures are investigated and confirmed through FTIR, ¹H-NMR, ¹³C-NMR and mass spectra measurements and analyses. The thermal evaporation technique was employed to prepare thin films of both compounds. FTIR analyses of the powder and thin film were utilized to study the thermal stability. The X-ray diffraction (XRD) revealed that both PPC and NPC have a triclinic crystal system in their powder form with different lattice parameters. Additionally, the thermal analysis, including thermogravimetric analysis (TGA) and differential thermal analysis (DTA), indicated that both PPC and NPC exhibit good thermal stability up to 490 K and 478 K, respectively. The dielectric properties and AC electrical conductivity of the thermally evaporated thin films of both compounds were assessed over a frequency range of approximately 100 kHz to 5 MHz and a temperature range of about 310 to 580 K. The observed frequency exponent behavior indicates that the correlated barrier hopping model (CBH) is the primary mechanism governing electrical transport for both compounds. Furthermore, parameters such as the maximum barrier height WM (WM is 0.4 eV for PPC and 1.3 eV for NPC), the characteristic relaxation time τo (τo is 10–7 s for PPC and 10–4 s for NPC), the hopping distance R, which is on the order of 10–9 cm, and the density of localized states N, approximately 10²⁶ eV cm⁻³, were calculated to provide a comprehensive understanding of the materials' electrical properties. These calculated parameters indicate that both materials could serve multifunctional roles in technological applications such as capacitors for energy storage, particularly in systems requiring rapid charge and discharge cycles, as well as in microwave and radio frequency applications.

Electrical investigation and enhancement of optical, structural, and dielectric properties of flexible PVDF/LiZnVO4 nanocomposites
Article
Full-text available
  • Jul 2023
Thin polymeric films of poly(vinylidene fluoride) (PVDF) containing variable mass fractions of nanoparticles (LiZnVO4) were successfully synthesized via the ordinary solution casting method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR), and ultraviolet–visible spectroscopy were used to explore the role of LiZnVO4 on the structural and optical characteristics of synthesized nanocomposites. In addition, dielectric permittivity (ε' and ε") and dielectric modulus (M' and M") were investigated. The XRD spectral data reveals the crystalline nature of pure LiZnVO4 with rhombohedral structure with an average size of 83 nm calculated using the Scherer'sa equation and W-L plot. The interaction between PVDF and LiZnVO4 was approved through the shift in characteristics in some IR bands. The decrease in band gap energies with increasing LiZnVO4 was attributed to the change of density in the localized states within the PVDF matrix. The effect of both frequency and temperature on the AC parameters was also investigated. Both ε' and ε" had their maximum values at low frequencies and decreased as the frequency and temperature increased. The results from XRD and FT-IR were correlated with changes in the dielectric characteristics at the maximum level value of LiZnVO4, suggesting the potential of these materials as basic components for lithium-ion batteries.

Article
Full-text available
Herein, pristine poly(vinyl alcohol) (PVA) and PVA‐zinc oxide (ZnO) nanocomposite thin films are prepared by solution casting method with different wt% of ZnO (0.1, 0.2, 0.3, 0.5 wt%) nanoparticles with PVA polymer matrix. The addition of ZnO in a PVA matrix induces decrease in the transparency of films. The structural characteristics of prepared thin films are analyzed by X‐ray diffraction (XRD), Fourier transform infrared (FTIR) and Raman spectroscopy. XRD confirms the presence of ZnO structure and β‐phase in the synthesized films. The average crystallite size of the prepared thin films were determined by Scherer's equation. XRD result shows increase in percentage crystallinity of the films. Vibrational modes and functional groups present in pristine PVA and PVA/ZnO thin films are identified by FT‐IR and Raman spectroscopy. FTIR analysis shows the characteristics bands, which corresponds to O–H and Zn–O bands present in the films. Raman spectra of pristine PVA and PVA/ZnO films are reported. Optical characteristics of synthesized pristine PVA and PVA/ZnO nanocomposite thin films are studied by UV–vis spectroscopy. Optical constants like absorption edge, direct bandgap, optical dielectric constant, loss, and optical conductivity were estimated, and optical dispersion parameters are calculated by single oscillator model.

Incorporated Au/Se nanoparticles into HPMC/CMC blend for enhancing structural, optical and morphological properties: Hybrid nanocomposites for optoelectronic applications
Article

  • OPT MATER
The present study employed a solution-casting approach to fabricate a hybrid polymer system using hydroxypropyl methylcellulose and sodium carboxymethyl cellulose (HPMC/CMC) with different weight percentages of gold/selenium (Au/Se) nanoparticles (50:50). The chemical reaction between the components of the nanocomposites was studied using Fourier transform infrared, X-ray diffraction, and UV/visible spectroscopic analyses, which indicated the prevalence of the amorphous areas. AFM and FESEM were used to check the homogeneity in addition to the morphology of the current samples. The optical energy gap was reduced because the resulting nanocomposite films mostly included amorphous areas rather than crystalline ones. The HPMC/CMC samples were carefully analysed for their band gap metallization criterion (Mc), optical conductivity, and refractive indices. The optical characteristics of the sample were improved, and the Urbach energy (Eurb) reached a new level of 2.045 eV for the film filled with 5 wt% of Au/Se NPs (HCAuSe-5), up from 0.415 eV for the pure HPMC/CMC blend. EDS mapping confirmed the successful incorporation of the (Au/Se) nanoparticles into the HPMC/CMC matrices. The roughness parameters, including surface kurtosis, surface skewness, root mean square, and average roughness, were calculated. The samples with 3 and 4 wt% of the nanofillers had a Rku value of 2.787243 and 2.87752, respectively, which got the best rough nature, lowered the Ra value, improved the contact characteristics, and made it more useful in high-tech applications, particularly in optoelectronics.

  • OPT LASER TECHNOL
Poly(vinyl alcohol), PVA doped with (0, 0.11, 0.55, 1.11, and 5.5) wt% of Toluidine Blue dye (TB dye) was prepared by the traditional casting method. The influence of Toluidine Blue dye concentration on spectroscopic, optical, and dialectical properties was investigated. Fourier transform infrared (FTIR) spectroscopies and X-ray diffraction were used to study the molecular and crystalline structure of PVA/Toluidine Blue dye composites. A UV–Visible spectrophotometer was used to investigate the optical characteristics. For all samples, the full-width half-maximum absorption spectra were determined. The direct and indirect allowed transitions have a multi-graded bandgap structure. Within the frequency range of 3 kHz to 10 MHz, the dielectric constant (ε′) and dielectric loss (ε″) were investigated and found to be dependent on the weight percent of TB dye. The correlated barrier hopping can describe the conduction mechanism for the studied samples. Furthermore, the PVA/5.5 wt% TB film demonstrated excellent optical CUT-OFF properties with a low transmission value in the spectral range (200–1300 nm), which is a favorable result for the fabrication of long-blocking optical filters and protective windows for optoelectronic and photonic devices like organic/polymer light-emitting devices, dye-sensitized solar cells, optical limiters, and optical switches.

A new nanocomposite was successfully synthesized by incorporating the prepared graphene oxide into poly(ethylene-co-vinyl alcohol) (EVOH) copolymer via simple solution casting method. XRD, FT-IR, SEM and TGA analysis were used to characterize the current nanocomposite. AC electrical transport properties of the nanocomposite were studied in the frequency range (10 Hz-1MHz) over the temperature range (298–423 K). The AC conductivity results were interpreted using jump relaxation model and were found to obey the universal double power law. The conduction mechanism inside the current samples has changed from non-overlapping small polaron tunneling to correlated barrier hopping.

Article
  • Dec 2020
  • OPTIK
A polymer electrolyte of PVA (Polyvinyl alcohol) doped with Tin (II) Bromide (SnBr2) at different weight ratios was synthesized by casting technique. The structure analysis of the composites was displayed by XRD (X-ray diffraction) and F.T. (Fourier transform)-IR techniques, which showed the decrement in the crystallinity with the argument of SnBr2 concentration and functional interaction between SnBr2 and PVA, respectively. The absorbance (Abs.) and transmittance (T%) in the range of wavelength 190−2500 nm were documented through the UV–vis spectrophotometer to research the influence of SnBr2 on the optical performance of PVA. The incorporation between SnBr2 and the main chain of the PVA matrix brings out a notable change in the optical properties of the polymer electrolytes. The optical band gap, refractive index (n), extinction coefficient (k), the real and imaginary parts of dielectric constant (εr and εi) as well as optical conductivity (σop) exposed a clear dependence on the SnBr2 content. Moreover, the dependence of dielectric properties on the contents of SnBr2 has been studied in the range of frequency from 100 Hz to 1 MHz. The conduction mechanism is mainly correlated Barrier Hopping (CBH) model. SnBr2/(PVA) polymeric solid electrolyte can be used for electronic and optoelectronic and electrochemical devices.

  • Feb 2020
Fabrication of polyvinyl alcohol (PVA)–polyethylene oxide (PEO) blend doped with tin dioxide (SnO2) nanocomposites has been investigated for flexible electrical and optical applications. The prepared nanocomposites have low cost, lightweight, flexible, high corrosion resistance, good optical and electrical properties. These properties of fabricated nanocomposites make it useful for different optoelectronics applications such as: sensors, solar cells, transistors, diodes, capacitors, energy storage etc. The structural, optical and electrical properties of (PVA–PEO–SnO2) nanocomposites have been studied. The experimental results of optical properties for (PVA–PEO–SnO2) nanocomposites showed that the nanocomposites have higher absorbance in UV region at wavelength range (200–280) nm. This behavior makes the nanocomposites may be used for optoelectronics applications. The absorbance, absorption coefficient, extinction coefficient, refractive index, real and imaginary dielectric constants and optical conductivity of polymer blend are increased with the increase in SnO2 nanoparticles concentrations while the transmittance and energy band gap are decreased with the increase in SnO2 nanoparticles concentrations. The decrease in energy band gap is useful for different optoelectronics devices industries. Also, the results showed that the dielectric constant and dielectric loss decrease while the conductivity increases with the increase in frequency. The dielectric constant, dielectric loss and conductivity are increased with the increase in SnO2 nanoparticles concentrations. The electrical properties showed that the (PVA–PEO–SnO2) nanocomposites have good dielectric parameters which it may be used for different electronics applications.
