“…Hence, as a result, during load application, stress concentration around GSP particles leads to toughness failure, as already explained in the previous section 4.3.3 for the elongation at break. The above results were also in agreement with the Maurya et al [ 53 ] and Mihalic et al, [ 54 ] where both the authors reported the decrease in the impact strength of the composites compared to the base matrix due to the addition of stiff natural fiber. It was presumed that crack propagation of the applied stress was promoted due to the presence of GSP and T‐GSP particles, hence, as a result, a decrease in tensile toughness is evident.…”

Current study employs reinforcement of untreated (GSP) and alkali treated groundnut shell powder (T-GSP) to the thermoplastic acrylonitrile-butadienestyrene (ABS) matrix for the fabrication of composites. Interactions of alkali to the cellulose, hemicellulose, and lignin of T-GSP was confirmed from the ATR-IR analysis. The most significant tensile strength (54.78 MPa) and modulus (2.78 GPa) was reported for 20 wt% T-GSP reinforced ABS composite. Additionally, greatest flexural strength and modulus of 88.30 MPa and 7.80 GPa was recorded for the composite constitutes 20 wt% T-GSP and 80 wt% ABS.The highest and lowest notched impact strength of 15.85 kJ/m 2 and 13.52 kJ/ m 2 were reported for the composites consist of 10 and 20 wt% of T-GSP. Composite 20/80 T-GSP/ABS exhibited highest shore D hardness value of 90. Morphology was studied using FE-SEM characterization and reports excellent wetting of T-GSP particles from ABS. Composites reinforced with 10 wt% of T-GSP exhibited highest (~269 C) while one reinforced with 20 wt% of the T-GSP showed lowest thermal degradation point (~259 C) throughout the temperature range. Differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA) analysis shows an increment (1-6 C) in the glass transition temperature of all the composites compared to pristine ABS irrespective of treatment.alkali-treatment, acrylonitrile-butadiene-styrene, groundnut shell powder, notched impact strength, thermoplastic composites | INTRODUCTIONComposites materials are essential in many forms for the survival of human life, and they may be structural, [1][2][3][4] functional, [5,6] or biomaterial. [7] However, the fabrication of synthetic fibers for polymer composite manufacturing leads to the generation of immense waste and energy consumption. Natural and sustainable reinforcement with high-mechanical strength could be the perfect and technoeconomic answer to these synthetic counterparts. Due to their environment-friendly and moderately good mechanical properties, they create a huge opportunity to implement them in different engineering and commercial applications. [8,9] For instance, industrial fibers like flax, Piyush Kumar is the first author.

“…Differential scanning calorimetry (DSC) analysis provides the thermal profile of investigated samples under isothermal scanning. [ 62 ] The composite specimen is heated, and the changes in heat flow are recorded. [ 63 ] The materials transformations like curing/polymerization, phase changes, glass transitions, melting, and so forth, can be identified from the changes in heat flow.…”

Silica phenolic ablative composites are used in many high‐temperature applications like rocket/missile solid motor nozzles, space re‐entry vehicles, and so forth. As ablative composite with lower thermal conductivity and density can save considerable cost, a hybrid silica phenolic ablative composite was developed by establishing a novel processing methodology using chopped silica fiber, phenolic resin, and hollow glass microsphere. The thermophysical properties of the developed hybrid composite are analyzed and established the scientific know‐how. The developed composites, with 36% lower density, displayed 50% lower thermal conductivity and 50% lower thermal diffusivity than standard silica phenolic composite. Since a proper thermal conductivity model for a three‐component composite with matrix, fiber, and hollow glass microsphere is not available, the most suitable model for the developed composite is established.

“…88 Many factors influence the formation of conductive paths, including dispersion, geometry, amount, and the nanofillers' inherent characteristics. [89][90][91][92][93][94][95] The formation of strong interphase between matrix and filler plays a determining role in the matrix's electrical properties. Choosing a proper fabrication method is critical as a homogeneous filler distribution will be obtained during the fabrication process.…”

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.
