“…Among them, the analysis of the dielectric constant is a significant way to comprehend the mechanism of ion transportation and the phase transitions of PE. The dielectric behavior-based real ( ε′ ) and imaginary ( ε″ ) parts of plasticized NCSPE were analyzed from the following equations [ 40 , 41 ]:

where C is a capacitance; d is the sample thickness; A is the electrode area; ε o is the permittivity of the free space which is equal to 8.856 × 10 −14 F/cm; C o = ɛ o A/d is the capacitance in vacuum; and ω = 2πf, in which f denotes the frequency [ 42 , 43 ]. Figure 2 , Figure 3 present both dielectric constant and dielectric loss ( ε′ , ε″ ) opposed to frequency at room temperature for the CS–40 wt.% AgNO 3 –% 3 wt.% Al 2 O 3 plasticized with different amounts of glycerol.…”

“…The influences of the electrode are suppressed with dielectric modulus formalism since, at low frequencies, they are associated with high capacitance [ 40 , 54 ]. Using the following equations, both real (M ’) and imaginary (M ’’) parts of complex modulus ( M* ) can be determined [ 55 , 56 ]:

where ( ε″ ) is dielectric loss and ( ε′ ) is the dielectric constant [ 43 ]. Figure 4 , Figure 5 show the real and imaginary parts ( M ’ and M ’’) of electrical modulus variation with frequency dependence at room temperature for all plasticized NCSPE films.…”

In the present work, chitosan (CS) as a natural biopolymer was used to prepare nanocomposite polymer electrolytes (NCPEs) in order to reduce plastic waste pollution. The plasticized CS-based NCSPE has been prepared via the solution casting technique. The electrical properties of the films were investigated using AC conductivity, dielectric properties, electric modulus, and electrical impedance spectroscopy (EIS). The obtained results from the dielectric properties and electric modulus study confirm the non-Debye behavior of ion dynamics. The effect of glycerol plasticizer on ionic conductivity of the CS:AgNO3:Al2O3 system was investigated via AC conductivity and impedance studies. The conductivity of the samples was explained based on electrical equivalent circuits and Bode plots. The electrochemical properties such as transfer number measurement (TNM), linear sweep voltammetry (LSV), and cyclic voltammetry (CV) were carried out to inspect the sample suitability for electrochemical double-layer capacitor (EDLC) application. The highest conductivity was 3.7 × 10−4 S cm−1 with the electrochemical stability window up to 2.1 V at room temperature. Through the TNM study, the ionic conductivity of plasticized CS-based NCSPE was confirmed, and ion transport (tion) of the highest conducting sample was found to be 0.985. The activated carbon electrode with the highest conducting sample was employed in the EDLC device fabrication. Accordingly, it can be said that the highest conducting sample had capable performance to be applied in electrochemical device application.

Advanced polymer composite membranes were prepared from a linear sulfonated poly(ether ether ketone) (SPEEK) with bismuth cobalt zinc oxide [BCZO, (Bi2O3)0.07(CoO)0.03(ZnO)0.90] nanopowder as an inorganic additive for the application of H2-O2 fuel cell. Morphology data tend to provide evidences for the incorporation of BCZO into SPEEK polymer. Indeed, composite membrane loaded with 7.5 wt.% of BCZO was identified to uptake maximum water, while the pristine SPEEK membrane occurred to retain only 24.0 %. As such SPEEK matrix loaded with 7.5 wt.% of BCZO was found to exhibit the maximum proton conductivity of 0.030 S cm-1, whereas the pristine membrane was restricted to 0.021 S cm-1. Evidently, TGA profile of the composite membrane was measured to exhibit sufficient thermal stability to employ as electrolyte in fuel cell. The membrane electrode assembly of pristine SPEEK and SP-BCZO-7.5 wt.% membranes were fabricated and studied for their electrochemical performance. Indeed, the characteristics of newly developed composite membranes led to possess incredible feature towards fuel cell applications.

PVC‐PMMA and PVC‐PMMA‐PbO PNC films were prepared. HR‐TEM confirmed the nanoparticle structure of PbO, while XRD assured its purity, tetragonal structure, with crystallites measuring 35.71 nm. SEM showed the blend surface appeared smooth and homogenous with a fingerprint shape, and loading increased the surface roughness. PbO was reported to be evenly distributed across the blend surface. FTIR confirmed that all blend functional groups are present and the formation of hydrogen bonds between PVC and PMMA, besides the strong interactions between PbO and blend chains. Different optical constants were investigated using UV–vis‐IR spectroscopy. The transmittance of the blend was 81.99% and decreased to 48.14% after loading 4 wt.% PbO (at 500 nm). Loading causes an increase in absorption. The extinction coefficient shows low extinction coefficients (k < 10−6). Loading PbO narrowed the blend band gaps and increased the refractive index n. The carrier's concentration to the electron effective mass was reported. Optical conductivity, energy loss functions, and nonlinear optical parameters were also studied. Tensile properties revealed that loading increased Young's modulus, tensile strength, and elongation at break. The enhancements in optical and mechanical characteristics of PNC films illustrate the possibility of extending their applications to include the semiconductor, electronics, and optics industries.
