“…Figure depicts the scanning electron microscopy (SEM) images of the obtained reduced graphene oxide (rGO) film, rGO/CNTs (GC) film and GCC film from the entire cross‐sectional view. The fracture edges of the rGO film exhibit a near‐parallel structure with a thickness of ≈32 ± 3 µm (Figure 2d,g,e), which is similar to the microstructure of rGO films prepared by other methods . As is shown in the inset image of Figure j, the pristine monolayer GO sheets were almost transparent.…”

resistance of carbon materials are perfect choices for electromagnetic interferences (EMI) shielding materials. [11][12][13][14] Therefore, flexible and preservative carbon films with excellent EMI shielding performance have been considered as promising substitutes for traditional metallic films.Carbon nanofibers and flexible graphite were employed to construct high-performance EMI shielding films at the early stage. [15] The EMI SE of flexible graphite can reach 130 dB at 1 GHz, [16] which is superior to almost all EMI shielding materials. Cao and co-workers prepared a flexible and lightweight (density < 0.1 g cm −3 )

“…Recently, the development of nanotechnologies and bionic design has enabled efficient solutions for the fire retardancy of engineering materials, especially wood, in a more environmentally friendly way . For example, hybridizing wood with inorganic nanoparticles made of clay, Mg–Al‐layered double‐hydroxide, and calcium carbonate has proven effective at forming functional inorganic/organic materials with good thermal resistance and fire retardancy .…”

Wood is one of the most abundant, sustainable, and aesthetically pleasing structural materials and is commonly used in building and furniture construction. Unfortunately, the fire hazard of wood is a major safety concern for its practical applications. Herein, an effective and environmentally friendly method is demonstrated to substantially improve the fire-retardant properties of wood materials by delignification and densification. The densification process eliminates the spaces between the cell walls, leading to a highly compact laminated structure that can block oxygen from infiltrating the material. In addition, an insulating wood char layer self-formed during the burning process obstructs the transport of heat and oxygen diffusion. These synergistic effects contribute to the material's excellent fire-retardant and self-extinguished properties, including a 2.08-fold enhancement in ignition time (t ig ) and 34.6% decrease in maximum heat release rate. Meanwhile, the densified wood shows a more than 82-fold enhancement in compressive strength compared with natural wood after exposure to flame for 90 s, which could effectively prevent the collapse and destruction of wooden structures, and gain precious rescue time when a fire occurs. The facile top-down chemical delignification and densification process enabling both substantially enhances fire-retardant performance and mechanical robustness represents a promising direction toward fire-retardant and high-strength structural materials.

“…Graphene has good flame‐retardant properties . Due to extraordinary lamellar barrier effect, graphene can impede the infusion of pyrolysis products, flammable gases, and oxygen . Graphene materials produce a consistent dense layer when exposed to fire, thus act like a barrier and restrict the passing of pyrolysis products from substrate.…”

Personal protective clothing is intended to protect the wearer from various hazards (mechanical, biological, chemical, thermal, radiological, etc.) and inhospitable environmental conditions that may cause harm or even death. There are various types of personal protective clothing, manufactured with different materials based on hazards and end user requirements. Conventional protective clothing has impediments such as high weight, bulky nature, lack of mobility, heat stress, low heat dissipation, high physical stress, diminishing dexterity, diminishing scope of vision, lack of breathability, and reduced protection against pathogens and hazards. By virtue of the superlative properties of graphene, fabrics modified with this material can be an effective means to overcome these limitations and to improve properties such as mechanical strength, antibacterial activity, flame resistance, conductivity, and UV resistance. The limitations of conventional personal protective equipment are discussed, followed by necessary measures which might be taken to improve personal protective equipment (PPE), the unique properties of graphene, methods of graphene incorporation in fabrics, and the current research status and potential of graphene‐modified performance textiles relevant to PPE.
