“…58 The form of the soft template was controllable and easy to remove due to the lowstrength and low-stiffness structure. In contrast, high strength and hardness solids were used in hard frameworks and eventually became a component of the composite material, such as MXene@PMMA hybrids, 59 3D VN/MXene, 60 and P-MXene/ CNF. 61…”

“…Poly(methyl methacrylate) (PMMA) is frequently used because of its lowtemperature burn-out, low ash content, and biocompatibility. [24][25][26] Porous materials achieved using PMMA with the sacrificial templating method have yielded a wide range of nanoscale pores, finding applications in catalyst materials, [27][28][29][30][31][32][33] films, [34,35] membranes, [36,37] oxides, [38][39][40] carbon-based structures, [41][42][43][44] bioactive glass, [45] electrode materials, [46,47] and scaffolds and foams. [48,49] In addition, microscale pores have been successfully fabricated using packed PMMA beads (5-800 μm) as pore-forming agents, resulting in porosities ranging from 7% to 80%.…”

Powder‐based 3D printing was combined with sacrificial templating to realize highly porous yttria‐stabilized ZrO2 (YSZ) ceramic foam objects with well‐defined geometries. The porous sacrificial template is 3D printed using poly(methyl methacrylate) powder. Various methods are evaluated to optimize ceramic slurry infiltration into the 3D‐printed template and subsequent burn‐out. The optimized method yields ceramic foam objects with an open porosity of >66% and replicates the geometry of the 3D‐printed template with high fidelity.

“…[8,11,[24][25][26][27][28] Due to their high electrical conductivity, MXenes exhibit multiple reflection mechanisms between layers and contribute to secondary interferences, which can be rectified by either structural design or composite strategies. [18] Various structural designs such as thin film, [4,11,19,29] solid pellet, [30] porous film, [31] foam, [7,8,32,33] sponge, [26,34] fabric, [35] aerogel, [36,37] membrane, [9,16,38] and paint [39] are explored for MXenes to attenuate electromagnetic interference. Structural design helps to produce a higher absorption-to-transmission ratio, interfacial scattering, and multiple reflective surfaces, successfully mitigating secondary EMI pollution.…”

The terahertz frequency range is gaining popularity in security, stealth technology, and the future 6G network communication. For the control of severe terahertz electromagnetic interference (EMI) pollution, frequency‐selective stealth‐capable shielding materials are being explored to mask terahertz signals. For the realization of masking terahertz signals, the robustness, lightweight, and shape‐conformable materials with excellent terahertz EMI shielding/absorption are crucial. Here, the study reports the fabrication of 3D symmetric pyramidal architectural MXene composite films with frequency‐selective stealth performance characteristics via the facile drop casting method. With the high absorption capability of 2D MXene layers, the MXene composite films exhibit substantial terahertz stealth performance. 3D pyramidal microstructure design leads to frequency selective surface‐assisted reflection resonance in the frequency range of 0.6–1.1 THz. The MXene composite film demonstrates an outstanding maximum terahertz shielding effectiveness (SE) of up to 70.4 dB and a specific SE of 0.55 dB µm−1. These terahertz SE values exceed all of those for MX‐based shielding material designs reported in the literature. The investigation will open a new direction toward developing terahertz EMI shielding thin films with easy integration into any surface for stealth capabilities.
