“…These groups are generated on the surface of CF and etched because of the strong oxidation effect of H2SO4/HNO3 [27]. The ATR-IR peaks of -OH functionalized CF using KOH and piranha solution is shown in and 878 cm -1 depicts the C=O stretching [28][29][30] and C-H bending [15,31]. It is important to note here that increase in the relative intensities of the bands at 1425 and 3300-3400 cm −1 compared to d-CF suggests that there are more -OH groups on the CF surface; all these observations confirm that the surface of the CFs has been functionalized or activated by the piranha solution [32].…”

The compatibility among nonpolar thermoplastics like polypropylene (PP) and carbon fibers (CF) having traditional sizing or coating is challenging. In this study, facile and effective surface functionalization of CF and its subsequent coating with functionalized carbon nanotubes (CNTs) were carried out to obtain improved interfacial shear strength (IFSS) which was validated by the single fiber fragmentation test (SFFT). Functional groups, -COOH, -OH, and -NH2, were separately grafted on the CF surface using different chemical routes. Additionally, ultrasonic assisted electrophoretic deposition (EPD) technique was used to coat -COOH, -OH, and -NH2 functionalized CNTs on the sized and surface functionalized CFs. Attenuated total reflection-infrared spectroscopy (ATR-IR), X-ray photoelectron spectroscopy (XPS), and field emission scanning electron microscopy (FE-SEM) images confirmed the successful surface functionalization and coating on CF. Neat PP and a blend of PP and maleic anhydride-grafted-styrene ethylene butylene styrene (MA-g-SEBS) were used as two different base polymer matrixes in preparing a total of 26 different SFFT samples. Silane functionalized CF coated with amine functionalized CNTs using ultrasonic assisted EPD process showed IFSS of ∼29 MPa which was an impressive ∼758% higher than pristine CF and highest among all the surface modified CFs. Interestingly, this translated into useful increase of ∼13% in single fiber tensile strength of functionalized and treated CF over and above that of as received CF.

“…PMMA is a widely used polymeric material owing to its excellent transparency throughout the λ vis. 65–67 The first significant use of PMMA took place during the Second World War for aircraft windows, submarine periscopes, gun turrets for airplanes, and so forth. It is known as acrylic glass, although PMMA is technically not a type of glass.…”

Flexible and optically transparent electrodes (TEs) are essential for most state-of-art organic optoelectronic devices (OOED). The demand for bendable electronic devices with aesthetic impact and multi-functionality has driven the rapid development of flexible TEs with improved optoelectrical and mechanical properties. However, conventional rigid TEs, that is, indium tin oxide (ITO) coated glass substrate (ITO/glass), cannot match smart devices' requirements in unique fields, like electrochromic devices, electronic skins, and wearable electronics, foldable displays, smart windows, and solar cells. To substitute extensively used ITO/glass electrodes has been endeavored because of the increasing price and inherently brittle ITO and glass substrate behavior. Emerging TEs based on the combination of the polymers substrate and conducting fillers like graphene, carbon nanotubes, metal nanowires, and transparent conducting oxides are bendable, lightweight, and inexpensive. They have shown substantial prospects to be used in the devices mentioned above. With each tiny development in these emerging TE's, such as outstanding optoelectrical and mechanical features in flexible electrodes, they become more suitable for practical applications in miscellaneous bendable devices. This review summarizes the comprehensive overview of the modern alternative flexible TEs and their implementation in bendable and stretchable devices.

The work reports on the preparation of polyaniline/lead iodide optoelectronic photodetector on antimony tin oxide (ATO) glass (PANI/PbI 2 /ATO) for providing a low-cost light sensor in the UV, Vis, and near IR regions (wide optical range photodetector).The deposition of PbI 2 nanoparticles was carried out on the surface of PANI using the ionic adsorption deposition method. Four ATO/PANI/PbI 2 composites (I, II, III, and IV) were produced by varying the Pb 2+ concentrations (0.01, 0.03, 0.05, and 0.07 M, respectively). The chemical structure, morphology, optical, and electrical properties were assessed using different analytical tools. Scanning electron microscopy (SEM) imaging revealed the formation of a nanoporous PANI network. After PbI 2 incorporation within the PANI network, white nanoparticles formed on the surface. The average size of the PbI 2 nanoparticles was 220, 270, 280, and 320 nm for Pb 2+ concentration of 0.01, 0.03, 0.05, and 0.07 M, respectively. Moreover, x-ray diffraction analysis confirmed PANI/PbI 2 composite formation, as witnessed by the appearance of new peaks at 12.77 , 34.31 , and 38.8 characteristic of PbI 2 .Through the optical analyses, the band gap values of the PANI/PbI 2 composites I, II, III, and IV were 2.63, 2.51, 2.46, and 2.48 eV, respectively. ATO/composite III was applied as an optoelectronic device for detection the light under different intensities or wavelengths, in which the current density (J ph ) increase from 2.5 to 3.42 mA cm À2 upon increasing of the light intensity from 25 to 100 mW.cm À2 , respectively. Moreover, the J ph recorded an optimum value of 3.33 mA cm À2 at 390 nm, which decreased to 2.09 mA cm À2 at 490 nm and increased again to 3.13 mA cm À2 at 636 nm. The optoelectronic photodetector exhibited an optimum incident photon to electron conversion efficiency (IPCE) of 10.7% at 390 nm. The photoresponsivity (R) and detectivity (D) were determined to be 107 mA cm À2 and 3.38 Â 10 10 Jones,
