Exploring electromagnetic interference (EMI) shielding materials with ultra-efficient EMI effectiveness (SE) and an absorption-dominated mechanism is urgently required for fundamentally tackling radiation pollution. Herein, zeolitic imidazolate framework-67 (ZIF-67)/MXene/cellulose aerogels were first prepared via a simple solution mixing-regeneration freeze-drying process. Subsequently, they are converted into electric/magnetic hybrid carbon (Co/C/MXene/cellulose-derived aerogels) through facile pyrolysis strategy. ZIF-67-derived porous Co/C could provide the additional magnetic loss capacity. The resultant exhibit hierarchically structure, complementary waves (EMWs) mechanisms, abundant heterointerfaces. construction of architecture synergy greatly alleviate impedance mismatching at air-specimen interface, which enables more EMWs to enter consumption. Moreover, numerous heterointerfaces among Co/C, Ti3C2Tx MXene, cellulose-derived skeleton induce generation multiple polarization losses containing interfacial dipole polarization, further dissipate EMWs. aerogel low density (85.6 mg/cm3) achieves ultrahigh SE 86.7 dB superior absorption coefficient 0.72 simultaneously. This work not only offers novel approach design high-performance entailing reflection characteristic but also broadens applicability in aerospace, precision electronic devices, military stealth instruments.

Multilayer Ultrathin MXene@AgNW@MoS₂ Composite Film for High-Efficiency Electromagnetic Shielding

Structure and material composition is crucial in realizing high electromagnetic interference (EMI) shielding effectiveness (SE). Herein, an ultrathin MXene@AgNW@MoS2 (MAM) composite film that resembles the structure of a pork belly exhibits superior EMI performance was fabricated via vacuum-assisted suction filtration process atomic layer deposition (ALD). The staggered AgNWs form skeletons intersperse MXene sheets to build doped with three-dimensional network structures, which improves electrical conductivity film. Based on optimal dispersion concentration Ag single layers, MXene/AgNW AgNW are alternately vacuum-assisted-filtered obtain laminated structures multiple heterogeneous interfaces. These interfaces generate interface polarization increase reflection scattering, resulting increased (EM) wave losses. On other hand, MoS2 outer nanolayers precisely by ALD effectively increases absorption proportion waves, reduces secondary reflection, stability properties. Ultimately, MAM (a thickness 0.03 mm) five alternating internal layers excellent SE 86.3 dB X-band.
