“…The transmittance values do not deviate much over the wavelength range studied, indicative of good coating quality. The phenomena responsible for the blocking of UV are as follows: (i) the ability of GNP to absorb and reflect UV radiations, − (ii) delocalization of π bonds in CNF causing UV absorption, , (iii) π–π* and polaron to π* transitions in PAni, ,− and (iv) π–π* and polaron band transitions in PPy. , These phenomena are thus synergistically responsible for blocking UV radiation in coated fabrics.…”

Textile-based shielding materials are gaining much importance for electromagnetic interference (EMI) shielding because of their increased flexibility compared to most existing materials. The multilayer-like architectures realized by coating textiles can be used strategically to enhance the attenuation of microwaves. Herein, we report a water-borne conductive coating capable of shielding both EM and UV radiation with good thermal stability for potential applications as smart textiles. This work tries to understand the effect of different textile pre-treatments to maximize the enhancements in properties. Cotton fabrics were initially subjected to in situ polymerization of aniline and pyrrole and subsequently coated with a carbonaceous layer containing graphene nanoplatelets and carbon nanofibers on both the sides. It was seen that both the conducting polymer layer and the carbonaceous coating work in tandem to enhance the thermal stability, UV blocking, and EMI shielding. The coated fabrics shows a shielding effectiveness of −22 dB at a thickness of 1.2 mm over a wide frequency range of 2.6−26.5 GHz, a limiting oxygen index of 26%, and remarkable UV-blocking properties with a blocking of 99.99%. Both the coating and the pre-treatment do not alter the fabric's wettability�the surface remains hydrophilic. The coating rendered the fabric with conductivity values showing a four-order jump from the control sample. The samples show a shielding effectiveness of −22 dB, accounting for more than 99% of the incident radiation being attenuated. The attenuation happens via an absorption-dominated mechanism. The coated textile exhibits excellent heat dissipation properties, with temperatures dropping from as high as 147 to 41 °C in just 60 s.

“…It is the thinnest 2D material among known minerals, with a large surface area and high mechanical strength. [ 26 ] GO, a graphene derivative, retains its original two‐dimensional structure, but its surface is rich in oxygen‐containing functional groups such as hydroxyl, carboxyl, and epoxy groups. Figure 15 shows the FTIR spectrum of GO.…”

In this article, we used the biaxial warp-knitted carbon/glass hybrid fibers as the reinforcement, the epoxy resin as the matrix, and the vacuum-assisted resin transfer-molding technique to prepare composite materials modified with different mass fractions of graphene oxide (GO) to investigate the influence of GO on the mechanical properties of carbon/glass hybrid fiber reinforced composites. The tensile and bending properties of the samples along the 0 and 90 directions were tested experimentally, and the macro-and micro-morphology characteristics of the fractured specimens were observed. The influence of GO modification on the strength and modulus of the composite material was analyzed. The results showed that GO modification improves the bonding strength of fiber/resin interface, tensile, and bending properties. Notably, when the filling content was 0.25 wt%, the tensile strength along the 0 and 90 directions increased by 8.97 and 4.78%, respectively. Similarly, the tensile modulus
