MOF-Derived Co/C and MXene co-Decorated Cellulose-Derived Hybrid Carbon Aerogel with a Multi-Interface Architecture toward Absorption-Dominated Ultra-Efficient Electromagnetic Interference Shielding

“…The extensive popularization of telecommunication electronics integrated with radio frequency chips has caused serious electromagnetic interference (EMI) radiation pollution, which not only interferes with the utilized efficiency of intelligent electronics but also poses serious damage to personal health. − The exploration of high-efficiency EMI shielding materials is imminently demanded to eliminate EMI radiation pollution. Particularly, thin thickness and lightweight are two vital indicators for EMI shielding materials employed in automobiles, aircraft, and new-generation electronic equipment applications.…”

“…Particularly, thin thickness and lightweight are two vital indicators for EMI shielding materials employed in automobiles, aircraft, and new-generation electronic equipment applications. In this regard, porous conductive polymer composites (CPCs), such as CPCs aerogels, foams, and sponges, have received enormous interest because of their merits of lightweight, favorable processability, exclusive three-dimensional (3D) structure, and adjustable EMI shielding performance. ,− …”

“…Although such hybrid carbon aerogels with perfect conductive paths reveal superior EMI SE, their EMWs absorption is tremendously weakened because of the absence of magnetic loss capacity and the inferior impedance matching at the air–specimen interface. The severe impedance mismatching irreversibly causes undesired secondary EMI radiation pollution, which complicates the electromagnetic surroundings. ,, Thus, it is of great value and urgency to manufacture highly efficient EMI shielding materials, entailing an absorption-dominant mechanism for fundamentally addressing the EMI radiation pollution.…”

“…The resultant carbon nanofiber@Co/C aerogel reveals an absorption coefficient as high as 0.79 . Furthermore, the introduction of magnetic MOF derivatives could construct more abundant multicomponent heterogeneous architectures and enrich EMW dissipation mechanisms, which can drastically promote interfacial polarization and induce more attenuation mechanisms, thus strengthening the consumption of EMWs. ,,,− Therefore, the incorporation of magnetic MOF derivatives into hybrid carbon aerogels may be a feasible approach to construct multiple-component heterostructures with electric/magnetic cooperative loss and achieve ultra-efficient EMI SE with highly absorbed capability.…”

Construction of a carbon nanosphere aerogel with magnetic response for efficient oil/water separation

“…19–25 An aerogel is a bulk porous material with a three-dimensional network structure, 26–30 which has been widely used as gas filter materials, photocatalysts, 31–33 catalyst carriers, conductive materials, 34,35 adsorbents and insulation materials in the field of environmental remediation. 36,37 As a kind of aerogel, the carbon aerogel possesses high porosity, large specific surface area, and excellent chemical stability and mechanical properties. 38–42 In view of the unique structural advantages of the carbon aerogel, it can be used as an oil adsorbent to achieve oil/water separation.…”
