“…This confirms the enhanced interaction by raising the concentration of the dye. Similar results were previously obtained for polymer composite films for PVOH/Carmine dye [34], PVOH/CR [54], PVOH/MB-6B [55], PVOH/Rose Bengal [56] and PVOH/TY dye films [38]. Table 3 summarizes the influence of various types of Table 3.…”

“…The intensities of C=O and C=C peaks indicate that (PVOH-PEG) has a resonating structure (alkene ↔ alkane) due to hydrogen bonds formation with hydroxyl groups [45]. The disappear of the absorption band at 877 cm −1 owing to the C-H vibration bending and stretching with the NGB addition is attributed to the high miscibility of NGB dye to the (PVOH-PEG) blend [34,43]. When dye molecules are incorporated into the polymer matrix, the hydroxyl band locations (stretching and bending mode vibrations) of the polymer composite films are shifted to the lower wavenumber.…”

“…On the other hand, the insertion of NGB dye molecules with high concentration in the (PVOH-PEG) blend produces a progressive rise in the intensity of the peak, implying a growth in the polymer's degree of crystallinity. The increase in crystalline phase might be attributed to local ordering in the polymer network caused by the interactions between the polymeric matrix and the doped dye molecules [34]. In this case, the NGB molecules will fill the interstitial spaces among the polymeric chains within the amorphous phase and connect them via hydrogen bonds.…”

Polymer composite films of polyvinyl alcohol (PVOH) – polyethylene glycol (PEG) /naphthol green B dye (NGB) were prepared using the solution cast technique with different concentrations of NGB (0 - 25 wt. (%)). XRD emphasized the semi-crystalline nature of the base polymer blend (PVOH-PEG) which increased by NGB addition. FTIR spectra of the investigated samples confirmed the formation of hydrogen bonds between the polymer blend hydroxyl groups and the NGB molecules. Optical properties are studied within wavelengths ranged from 245 nm to 1500 nm. Multi-optical energy band gaps (Eg ) were observed in (PVOH-PEG) doped with NGB dye for the allowed indirect and direct transitions and showed a decrease with the addition of NGB dye. Analysis of the refractive index n offered a normal dispersion within the investigated wavelength region. The dependence of the dielectric constant ε', loss ε'' and ac conductivity σac on frequency (100 Hz - 1 MHz) and NGB content were investigated at room temperature (RT). The addition of NGB tends to increase σac of the (PVOH-PEG) blend, that serve in various semiconductor devices. The values of the frequency exponent s and the charge carriers binding energy WM decrease in the presence of NGB dye and are interpreted by the correlated barrier hopping (CBH) model. Electric modulus formalism clarified the presence of a single relaxation peak with a relaxation time  depends on the NGB wt. (%). The (current density J - electric field E) characteristics were studied at RT and showed a non-ohmic behavior. The current density J increased with the addition of NGB dye and the dc conduction is discussed in view of Schottky-Richardson and Poole–Frenkel theoretical models.

“…XRD spectra of the synthesized TiO 2 NPs and the PVC/PMMA polymeric blend filled with varying amounts of TiO 2 NPs can be seen in Figure 1. The pure PVC/PMMA blend displays small broad peaks at 2θ = 17.13 and 24.31, indicating that the blend is amorphous 23 . The XRD study of the pure TiO 2 nanoparticles identified distinct peaks at 25, 36, 37, 38, 48, 54, 55, 62, 69, 70, and 75, representing (101), (103), (004), (112), (200), (105), (211), (213), (116), (220), and (215) planes, respectively.…”

In the present work, sol–gel‐synthesized titanium oxide nanoparticles (TiO2 NPs) were added to polyvinyl chloride (PVC) and polymethyl methacrylate (PMMA) to create polymer nanocomposites (PNCs) samples. The preparation was carried out via the solution casting method. The synthesized TiO2 NPs have a tetragonal anatase phase and an average grain size of 15.7 nm. XRD analysis reveals that the TiO2 NPs' addition to PVC/PMMA causes a decrease in the crystallinity of PNCs films. Infrared Fourier analysis demonstrated the interplay/complexity between the PVC/PMMA blend and TiO2 NPs. The UV/visible spectrum of the PVC/PMMA blend showed two absorbance peaks at 278 and 208 nm, which may result from the n → π* and π → π* transitions. Also, optical bandgaps for indirect and direct allowed transitions decreased with increasing TiO2 NPs concentration. The samples' AC electrical conductivity and dielectric properties were measured at room temperature. As the TiO2 NPs content in the nanocomposite rises, a percolating network begins to emerge inside the composite, demonstrating that AC electrical conductivity obeys Jonscher's law. Additionally, it has been demonstrated that nanoparticle concentration leads to a higher composite dielectric loss and dielectric constant. These findings suggest the possibility of using the prepared nanocomposites in capacitive energy storage and optoelectronic devices.Highlights PVC/PMMA‐TiO2 nanocomposites' films were fabricated via the solution casting method. Adding TiO2 NPs to PVC/PMMA reduces the crystallinity of the PNCs films. The allowed direct and indirect bandgaps decreased with rising TiO2 NPs content. AC conductivity, impedance, and dielectric characteristics were discussed. The findings indicate the use of prepared samples in optoelectronic devices.

“…In previous works, different kinds of materials as fillers in polymers have been explored for such applications [13][14][15][16]. These fillers involve organic dyes as erythrosine B and carmine [17,18]. While the majority of the explored ones focused on inorganic materials whether they are metals or semiconductors.…”

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.
