Abstract Considering the serious electromagnetic wave (EMW) pollution problems and complex application condition, there is a pressing need to amalgamate multiple functionalities within single substance. However, effective integration of diverse functions into designed EMW absorption materials still faces huge challenges. Herein, reduced graphene oxide/carbon foams (RGO/CFs) with two-dimensional/three-dimensional (2D/3D) van der Waals (vdWs) heterostructures were meticulously engineered synthesized utilizing an efficient methodology involving freeze-drying, immersing absorption, secondary followed by carbonization treatment. Thanks their excellent linkage effect amplified dielectric loss optimized impedance matching, 2D/3D RGO/CFs vdWs demonstrated commendable performances, achieving broad bandwidth 6.2 GHz reflection − 50.58 dB low matching thicknesses. Furthermore, obtained also displayed significant radar stealth properties, good corrosion resistance performances as well outstanding thermal insulation capabilities, displaying great potential in variable environments. Accordingly, this work not only straightforward method for fabricating heterostructures, but outlined powerful mixed-dimensional assembly strategy engineering multifunctional protection, aerospace other conditions.

Delicately aligned structures of two-dimensional (2D) MXene nanosheets have demonstrated positive effects on applications, especially in electromagnetic interference (EMI) shielding and infrared (IR) stealth. However, precise regulation structural assembly by theory-guided solution processing is still a great challenge. Herein, one-dimensional (1D) cellulose nanofibers (CNFs) with high aspect ratio are applied as reinforcing agent rheological modifier for MXene/CNF colloids to fabricate MXene-based materials EMI IR Notably, systematical study the proposed determine optimal solution-processing conditions finely oriented component arrangement requirements provides in-depth information interactions between components. The delicately regulated orientation structure assembled shear inducement convincingly through micro-CT wide-angle X-ray diffraction/small-angle scattering (WAXD/SAXS), which endows film significantly enhanced electrical conductivity 46 685 S m-1, tensile strength 281.7 MPa, Young's modulus 14.8 GPa. Furthermore, highly ultrathin possesses enhancement effectiveness (50.2 dB) stealth (0.562 emissivity). These findings provide fruitful understanding optimized fabrication high-performance functional composite films open up opportunity development multifunctional materials.

Micro–Nano Water Film Enabled High-Performance Interfacial Solar Evaporation

Nano-Micro Letters, Год журнала: 2023, Номер 15(1)

Опубликована: Сен. 22, 2023

Interfacial solar evaporation holds great promise to address the freshwater shortage. However, most interfacial evaporators are always filled with water throughout process, thus bringing unavoidable heat loss. Herein, we propose a novel structure based on micro-nano film, which demonstrates significantly improved performance, as experimentally verified by polypyrrole- and polydopamine-coated polydimethylsiloxane sponge. The 2D evaporator as-prepared sponge realizes an enhanced rate of 2.18 kg m-2 h-1 under 1 sun fine-tuning film. Then, homemade device condensation function is engineered for outdoor clean production. Throughout continuous test 40 days, this high production (WPR) 15.9-19.4 kW-1 m-2. Based outcomes, further establish multi-objective model assess global WPR. It predicted that m2 can produce at 7.8 per day, could meet daily drinking needs 3 people. Finally, technology greatly alleviate current energy crisis through large-scale applications.
