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.

“…These features involve the structural, optical, electrical and mechanical properties. The superiority of polymer composites over traditional organic and inorganic materials qualifies them to be active candidates in various applications [1][2][3][4]. Some of these applications are included in communications, industry, medicine and electronics.…”

“…Alharthi et al [3] explored the electrical and photoluminescence behaviors of Ag 2 S/PVA for visible-light optoelectronics. Also, Fe 2 O 3 nanoparticles, carbon quantum dots and other dopants were used to enhance the physical properties of host polymers for multi applications [1,[7][8][9][10]. Polyvinylalcohol (PVA), chitosan and polyvinylpyrrolidine (PVP) polymers play the leader-role as host matrices for dopants material due to their novel properties as low-cost, water-solubility, non-toxicity, bio-compatibility and hence environment-friendly.…”

The optical properties of polyvinylpyrrolidine (PVP) polymer have been enhanced using ternary Zn 1-x Sn x S as a filler for UVregion optical applications. Solution casting technique is used to prepare different Sn molar ratios (x: 0-0.3) in Zn 1-x Sn x S filled PVP polymeric composite films (1.0 wt.%). SEM, FT-IR and UV-visible-NIR spectrophotometry is utilized to characterize the optical properties of the plain PVP and polymeric composite films. SEM images reveal the homogeneous dispersion of the filler (Zn 1-x Sn x S) in the host PVP matrix. The FT-IR spectroscopic measurements ensure the successful interaction of ternary Zn 1-x Sn x S material and the host PVP polymer. The cut off transmittance edge is shifted from 260 nm (host PVP) to 390 nm (polymeric composite). The direct optical energy bandgap of the prepared polymeric composite films are shifted from 4.78 eV (plain PVP) to 3.45 eV for Zn 0.7 Sn 0.3 S polymeric composite film. An enhancement of the refractive index (n) and the optical conductivity (σ opt.) of the polymeric composite films is achieved as compared with those of the plain one. The single oscillator (E 0) and dispersion (E d) energies of the polymeric composite films were determined using Wemple and DiDomenico (WDD) model. The prepared polymeric composite films are strongly recommended for UV-region optical applications.

The films of vinylidene fluoride and trifluoroethylene (P(VDF-TrFE)) are widely used in piezoelectric tactile sensors, vibration energy harvesters, optical frequency conversion materials and organic photo-voltaic device because of high electroactive, good optical and nonlinear optical properties, respectively. In this work, the multilayer structured ultrathin films were fabricated by the Langmuir–Blodgett technique, and the thickness per layer can be controlled accurately. It was found that as the collapse pressure of P(VDF-TrFE) (25:75) and the optimal dipping value are 65~70 mN/m and 15 mN/m, respectively, a high-density film can be obtained due to the compression of molecules. The surface topography and optical properties of the LB films were characterized by X-ray diffraction, white light interferometer and variable-angle spectrum ellipsometer. It was observed that the films are transparent in the visible region and IR-band, but show a high absorption in the UV band. Besides, the transmittance of the films ranges from 50% to 85% in the visible region, and it linearly decreases with the number of monolayers. The average thickness of per deposition layer is 2.447, 2.688 and 2.072 nm, respectively, under three measurement methods. The calculated refractive index ranged from 1.443 to 1.598 (600~650 nm) by the Cauchy-model.
