In this research, well-crystallized zinc oxide nanorods (ZnO NRs) were produced via a solid-state synthesis. Then, employing the casting method, doped chitosan/polyvinyl pyrrolidone (Cs/PVP) blended polymers with different concentrations of ZnO NRs created. The wurtzite structure was determined using XRD. sample became increasingly amorphous up to content 1.5 wt% NRs, as shown by XRD examination. TEM measurements show that their lengths range from 200 300 nm and diameters are between 40 80 nm. FTIR analysis has been used study relationship polymer blend NRs. absorbance, transmittance, reflectance spectra obtained diffused technique utilized optical characteristics. With addition matrix, band-gap narrows while Urbach energy (tail bandwidth), extinction coefficient, refractive index, conductivity increase. A photoemission peak at about 470 visible in PL films made nanocomposites. At normal temperature, nanocomposites containing had greater ionic 4.2 × 10−5 Scm−1. Studies on electric modulus dielectric permittivity have also conducted order comprehend relaxation charge storage Cs/PVP-ZnO nanocomposite is more suitable for use thin-film solar cell applications device because decrease band gap values typically accompanied an increase conductivity.

Abstract The best materials for enhanced energy storage capacitors in electrical systems are polymer nanocomposites films. Therefore, using the solution casting approach, we created a unique series of FeVO 4 nanofiller‐embedded polyurethane (PU) and polymethyl methacrylate (PMMA)‐based composites. Various techniques were used to describe prepared XRD spectra assess crystallinity crystallite size nanocomposites. With rising nanoparticles (NPs) content up samples with 1.5 weight percent , demonstrated an increase amorphous phase mixture, which was further supported by UV–Vis measurements. FTIR determining complexation mixture. Calculations determine optical properties such as Urbach bandgap. rise NP concentration, bandgap decreases while increases. All samples' AC conductivity exhibit Jonscher's power law (JPL) behavior.

Abstract The Polyethylene glycol (PEG) and Chitosan (CS)/silver nitrate (AgNO 3 ) thin films were prepared by utilizing the casting technique to enhance their optical, dielectric, electrical properties. Their physicochemical characteristics investigated using a variety of techniques. FT‐IR study demonstrates that addition AgNO NPs results in discernible difference intensities locations vibrational peaks all bands, supporting incorporation inside PEG/CS. XRD analysis indicates peak at 2θ = 23.1° broadens strengthens proportionally with increase NPs. This observation suggests into PEG/CS greater degree amorphous compared blend. Additionally, when amount increases PEG/CS, energy band gap decreases, resulting creation localized states between valence conduction bands. These polymer nanocomposite films' conductivity, dielectric constant, loss increased frequency showed variance for various composite concentrations. NPs/PEG/CS can be promising options frequency‐tunable nanodielectrics, flexible substrates, bandgap‐regulated materials upcoming microelectronic, capacitive storage, optoelectronic technologies, according experimental results. Highlights nanocomposites obtained. optical properties calculated. Optical energy‐gap samples was reduced after adding are improved. suggested used storage devices.
