“…These XRD peaks are well‐matched with (1 0 1) and (2 0 0) characteristic planes of PVA polymer, respectively. [ 65,66 ] While the shoulder observed at 26.70° in the XRD patterns of the prepared films is referred to the characteristic peak of (0 0 2) plane of the graphene sheets (JCPDS 75‐1621), [ 67 ] which implies the successful interaction with that of the PVA structure. However, it is noted from the XRD patterns that the intensity of the characteristic XRD peak of PVA is decreased with increasing fillers' concentration from 0 to 10 wt%.…”

The effect of iron oxide nanoparticles (Fe2O3 NPs) content on the structural and optical parameters of polyvinyl alcohol/graphene (PVA/G) blend has been investigated. Fe2O3 NPs were synthesized by the hydrothermal procedure. Nanocomposite (NC) films of PVA/G filled with different amounts of Fe2O3 NPs were equipped using the solution casting technique. The surface morphology, structural, and optical properties were examined by scanning electron microscope (SEM), X‐ray diffraction (XRD), and ultraviolet‐visible‐near‐IR (UV‐Vis‐NIR) spectrophotometry techniques, respectively. SEM micrographs reveal the homogenous distribution of Fe2O3 NPs in the PVA/G matrix. The XRD analysis exhibits the formulation of the hematite phase of Fe2O3 NPs and the semi‐crystalline nature of PVA/G NC films. The UV‐Vis‐NIR data analysis shows that the optical properties of the PVA/G blend could be tailored via Fe2O3 NPs filling. Wemple–DiDomenico model is utilized to explore the dispersion parameters of the prepared NCs. A significant effect of Fe2O3 NPs filling is realized on the oscillator and dispersion energies, infinite refractive index, dielectric constant, average oscillator strength and the lattice dielectric constant of the NC films. PVA/G filled Fe2O3 NPs are suggested for different optical and storage applications.

“…The most convenient way to probe the structure of the band of polymeric materials is by examining the absorption index/coefficient that could be used to estimate the energy of the bandgap and evaluate the types of electronic transitions 30 . The coefficient of absorption α has been calculated by absorbance A with the equation Beer‐Lambert 31 :

α = 2.303 \frac{A}{X},

where X is the thickness of the sample. Figure 7 displays the SPL‐0 (Pure PVAL) and doped PVAL/LiNO 3 optical absorption coefficient, depending on photon energy.…”

In this paper, pure and 0.04%, 0.19%, 0.4%, 1.9%, and 4% LiNO3‐doped PVAL (polyvinyl alcohol) electrolyte were fabricated in the form of solid films by the casting process. The influence of Li+‐ions on PVAL was identified by some characterization tools such as X‐ray diffraction, FT‐IR (Fourier transform infrared), scanning electron microscope (SEM), thermal gravimetric analysis (TGA), UV‐visible‐NIR spectroscopy, dielectric, and conductivity measurements. X‐ray diffraction studies indicate that the semicrystalline of PVAL and the calculated crystallize size from Gaussian fitting were decreased with Li+‐ions concentration. FT‐IR results indicate that there is strong interaction among doping ions and the matrix. The surface morphology of the electrolyte films was studied via SEM. The optical studies demonstrate that the transmittance of films decreased with the rising of Li+‐ions. Urbach's energy and bandgap are also reduced with adding more ions. Different empirical equations were used to study the relation between the energy gap and the refractive index. The index of refraction of the films has average values in 2.024 to 2.078 range. Li+‐ion concentrations critically influenced the factors of nonlinearity. The calculated values of nonlinear optical susceptibility χ(3) and refractive index n2 were increased from 8.6 × 10−13 esu and 1.55 × 10−11 to 20.56 × 10−10 esu and 2.05 × 10−11, respectively. The dielectric constant and loss measurements of the PVAL embedded with 4% of LiNO3 (SPL‐5) were decreased exponentially with increasing the incident frequency. The AC electrical conductivity (σAC) and nonlinear I‐V curves are enhanced by increasing the Li+‐ion contents. The electrical current was increased with small resistivity for SPL‐5 film. The studied films have an inimitable result in various fields, such as nonlinear optical and varistor devices.

“…PVA composite films doped with ZrO 2 particles (0, 0.037, 0.185, 0.37, 1.85, 3.7, and 18.5 wt%) were prepared using the solution casting method. Increasing ZrO 2 content in PVA improved optical limitation and can accordingly be used as a material for optical filters [122].…”

Nanotechnology has facilitated unique ways of developing novel nano-composites. In that sense, polymer-based nano-composites are being extensively researched for their outstanding properties as a result of incorporating nano-fillers in the polymer matrix. They have activated enormous research interests owing to their potential in addressing environmental issues, packaging, optics, electronics, battery electrolytes, pneumatic actuation, molecular separations, sensors, biomedical applications, etc. Hence, the authors intend to consolidate reported information about these polymer matrices, diverse inorganic nanofillers, and nano-filled polymer composites for improvement in properties and future advanced applications. The review exhaustively covers 15 years of literature on theoretical, experimental, and application aspects of PVA & PMMA-based nano-composites. It also summarizes the structure-property correlations that govern their performance. Hence this review is hoped to provide the readers with stimulating insights on strategies, noteworthy challenges, and future opportunities/prospects in developing polymer nano-composites that may cater to the need of our society and scientific industries as well.
