“…In addition, it can be said that the quantum dots are clamped in the PVB network. 20 Figure 3e-h shows the morphological changes of nanocomposite films after different UV degradation times at a certain BNQDs loading concentration. Before UV degradation, polymer and nanocomposite film materials showed a smoother and layered cross-sectional area, while characteristic surface cracks appeared after different UV degradation times.…”

“…The decrease in bandgap as the graphene quantum dot loading rate increased showed that the obtained composites were promising for PL applications. 20 One of the economical and practical aspects of obtaining a high-performance UV protection material is to add UV protection fillers into the polymer matrix. 21 With this motivation, in this study, BNQDs were added into the polymer at different ratios to benefit from the UV protective and photoluminescence properties of quantum dots, as mentioned above.…”

The present investigation focused on the effect of boron nitride quantum dots (BNQDs) as a filler on the optical properties of polyvinyl butyral (PVB) nanocomposites. Herein, polymer nanocomposite films with advanced UV protection and high photoluminescence properties were successfully synthesized. Polymer nanocomposite films were produced by adding BNQDs to the polymer in different ratios by a simple solution forming and casting method. The films were decomposed at different UV degradation times, and their UV protective properties were tested. The structural, morphological, optical and chemical interaction of BNQDs/PVB nanocomposites was confirmed by Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Fourier Transform Infrared (FTIR), micro‐Raman spectroscopy, ultraviolet and visible (UV–Vis), and photoluminescence (PL) analyzes. As the amount of BNQDs in the polymer increased, the intensity of the bright images separated from the polymer also increased. TEM images confirmed the good distribution of quantum dots in PVB polymer matrix. Polymer composites doped with 0.25% and 0.4% BNQDs show excellent UV‐shielding properties as the transmittance in the UV region decreased about 69% and 95%, respectively. As the addition of BNQDs into the polymer increased, the PL emission of the pure PVB film, which showed almost no emission, increased significantly.

“…Figure 7 shows Raman spectra of 1, 2 and 3 layers of the (a) B1 (b) B2, (c) B3 and (d) V paints. The Raman spectra of all samples show three distinct Raman peaks for the D band (disordered graphitic site sp3) at around 1384 cm −1 , G band (graphitic site sp2) at around 1518 cm −1 , and 2D band at 2680 cm −1 , which indicate the number of stacked graphitic layers respectively [ 28 ].…”

The present manuscript reports on optimized formulations of alcohol-based conductive paints for electromagnetic interference shielding (EMI), which can ensure compatibility and reduce the visibility of electronic equipment, as a continuation of our previous work in this field, which examined water-based formulations for other applications. Graphite, carbon black, graphene, Fe3O4, Fe ore, and PEDOT:PSS in various ratios and combinations were employed in an alcohol base for developing homogeneous paint-like fluid mixtures that could be easily applied to surfaces with a paintbrush, leading to homogeneous, uniform, opaque layers, drying fast in the air at room temperature; these layers had a reasonably good electrical conductivity and, subsequently, an efficient EMI-shielding performance. Uniform, homogeneous and conductive layers with a thickness of over 1 mm without exfoliations and cracking were prepared with the developed paints, offering an attenuation of up to 50 dB of incoming GHz electromagnetic radiation. The structural and morphological characteristics of the paints, which were studied in detail, indicated that these are not simple physical mixtures of the ingredients but new composite materials. Finally, mechano-climatic and environmental tests on the coatings demonstrated their quality, since temperature, humidity and vibration stressors did not affect them; this result proves that these coatings are suitable for commercial products.

In the present work, we have prepared polymer blend of polyvinyl butyral (PVB) and poly (3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT: PSS) by solution casting route. Blends were tested for various structural, morphological, and electrochemical techniques. Structural properties were investigated by XRD technique exploring the contribution conducting polymer in host system PVB exhibit amorphous nature. COO functional group contributed in blend configuration was confirmed by FTIR technique. Clustering of PEDOT:PSS in blend system were observed by scanning electron microscopy.Subatomic surface topology and increased roughness due to blending concentration of conducting polymer were analyzed by probe microscopy techniques.Increased softness of blends was confirmed by shore "A" durometer test. PVB/PEDOT:PSS blend was drop casted on glassy carbon electrode and employed for detection of various metal ions. It was deployed for electrochemical sensing of Cu 2+ ion. Electrochemical sensing investigation was done by differential pulse voltammetry technique. Performance of blends at 4.5 pH, 200 s deposition time and À1.2 V deposition potential was more accurate and sensitive toward detection of Cu 2+ ion. The developed electrochemical sensor exhibited rapid sensing response in the range of 1.6 to 8.3 μM. Furthermor,e an influence of many analytical parameters such as pH, deposition time and deposition potential on Cu 2+ ion investigation were disclosed. This investigation may be feasible to construct a very simple, fast, and efficient electrochemical sensing system for toxic heavy metals at low-level concentration.
