Designing and developing high-performance shielding materials against electromagnetic interference is of utmost importance due to the rapid advancement wireless telecommunication technologies. Such hold both fundamental technological significance. A three-stage process presented for creating ultralight, flexible aerogels from biomass shield interference. Collagen fibers sourced leather solid waste are used for: (i) freeze-drying preparation collagen fibers/poly(vinyl alcohol) (PVA) aerogels, (ii) adsorption silver nanowires (AgNWs) onto fiber/PVA (iii) Hydrophobic modification fiber/PVA/AgNWs with 1H, 2H, 2H-perfluorodecyltriethoxysilane (POTS). Scanning electron microscopy studies reveal that an interweaving AgNWs porous network has formed a conductive network, exhibiting electrical conductivity 103 S·m–1. The effectiveness reached more than 62 dB, while density was merely 5.8 mg/cm3. fiber/PVA/AgNWs/POTS aerogel displayed even better efficiency 73 dB water contact angle 147°. study results emphasize distinctive capacity generate cost-effective, ecofriendly, highly efficient materials.

One of the most critical problems faced by modern civilization is depletion freshwater resources due to their continuous consumption and contamination with different organic inorganic pollutants. This paper considers potential already discovered MXenes in combination carbon nanomaterials address this problem. MXene appears be a highly promising candidate for water purification its large surface area electrochemical activity. However, swelling, stability, high cost, scalability need overcome. The synthesis methods composites graphene oxide, nanotubes, nanofibers, cellulose along structure, properties, mechanisms removing various pollutants from water, are described. review discusses methods, using composites. It also explores fundamental aspects MXene/carbon nanocomposites forms, such as membranes, aerogels, textiles. A comparative analysis latest research on topic shows progress field limitations practical application solve problem drinking scarcity. Consequently, demonstrates relevance promise material underscores importance further development provide effective treatment solutions.

Abstract Developing lightweight, high‐performance electromagnetic wave (EMW) absorbing materials those can absorb the adverse radiation or waves are of great significance. Transition metal carbides and/or nitrides (MXenes) a novel type 2D nanosheets associated with large aspect ratio, abundant polar functional groups, adjustable conductivity, and remarkable mechanical properties. This contributes to high‐efficiency assembly MXene‐based aerogels possessing ultra‐low density, specific surface area, tunable unique 3D porous microstructure, which is beneficial for promoting EMW absorption. Therefore, absorption have attracted widespread attention. review provides an overview research progress on absorption, focusing recent advances in component structure design strategies, summarizes main strategies constructing aerogels. In addition, based mechanisms regulation preparation methods properties varieties components pore structures detailed advance understanding relationships composition‐structure‐performance. Furthermore, future development challenges faced by summarized prospected.

Ceramic aerogels are promising high-temperature thermal insulation materials due to their outstanding stability and oxidation resistance. However, restricted by nanoparticle-assembled network structures, conventional ceramic commonly suffer from inherent brittleness, volume shrinkage, structural collapse at high temperatures. Here, overcome such obstacles, 3D ultralight highly porous carbon tube foams (CTFs) were designed synthesized as the carbonaceous precursors, where melamine used sacrificial templates form hollow thin-wall structures in CTFs (density: ∼4.8 mg cm-3). Then, arbitrary-shaped silicon carbide (SiC) nanofibrous (SNFAs) obtained through a simple chemical vapor deposition (CVD) process on CTFs. The resulting SNFAs exhibited excellent comprehensive performances: ultralow density (4.2 cm-3) conductivity (21.3 mW m-1 K-1 room temperature), rigidity (specific modulus: 13.2 kN·m kg-1), resilient compressibility. could support over 2100 times weight without visible deformation. Furthermore, also showed exceptional stability, which means that they withstand 1100 °C an air atmosphere 1550 inert atmosphere. These superior performances enable be suitable for harsh environments.

Polyimide (PI) aerogel with high thermal stability and low conductivity exhibits significant application value in the aerospace field. Nevertheless, traditional preparation methods of PI face challenges a complicated manufacturing process mechanical strength, which severely restrict their industrial scalability.
