Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 9, 2024

Abstract With the increasingly serious secondary pollution of electromagnetic waves (EMWs), efficient green shielding materials have become an urgent need. MXene is widely used in interference (EMI) due to its large surface area and high conductivity. Here, this work constructs islands with better performance through viscosity control continuous mechanical stirring. Benefiting from islands, Janus‐structural gel humidity response successfully prepared, showing controllable ultrahigh property (up 100.5 dB, thickness 2 mm). Interestingly, can spontaneously adjust water content according humidity, resulting a reversible transformation three states meet needs different environments. By design reasonable material combination, demonstrates excellent electrothermal (rise 111.6 °C, 5 s, V)/thermal insulation (thermal conductivity low 0.029 W m −1 K ) properties underwater/fire operations.

Three-Dimensional Macroporous Reduced Graphene Oxide-Mxene Aerogel Decorated with Hollow Mesoporous Carbon Spheres for Absorption-Dominant Electromagnetic Interference Shielding and Efficient Oil/Water Separation

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(33), P. 12683 - 12694

Published: Aug. 6, 2024

Herein, hollow mesoporous carbon sphere (HMCS)/Mxene/rGO aerogels were fabricated by simple hydrothermal reduction self-assembly and freeze-drying treatment. Owing to the unique architecture, HMCS nanoparticles can offer additional incident channels absorption cavities, enhancing electromagnetic wave (EMW) loss capacity. Moreover, fabrication of 3D porous structures synergy multiple losses extremely reduce impedance mismatching, resulting in more EMWs into matrix for consumption. In addition, abundant heterointerfaces between rGO, Mxene, HMCSs lead formation polarization losses, which further improve interference shielding efficiency (EMI SE). Therefore, benefiting from hierarchical cooperative mechanism, heterointerfaces, resultant EMI SE rGO-Mxene-HMCS aerogel reaches 80 dB at 8.2–12.4 GHz, is 2.5 times that pure rGO aerogel. More interestingly, owing their hydrophobicity promising structure, composites efficiently select adsorb various oils organic solvents oil/water mixtures realize separation. Remarkably, exhibits an impressive capacity up 100–160 its weight, it also shows admirable recyclability. Thus, great potential application

3D Printing-Assisted Honeycomb-Structured Bricklike Aerogels Applied for Infrared Stealth with Good Thermal Management

ACS Applied Polymer Materials, Journal Year: 2024, Volume and Issue: 6(22), P. 13828 - 13840

Published: Nov. 6, 2024

Delicate structure design with lightweightness and good thermal management for infrared (IR) stealth are two important factors since relying solely on low emissivity surfaces to suppress radiation will lead heat buildup erratic performance. Inspired by honeycomb bricks, an IR aerogel of MXene@poly(vinyl alcohol) (PVA)/phase change material (PCM) is prepared a 3D-printed mold, freeze-drying, vacuum impregnation. The as-prepared aerogels have excellent properties including high latent (105.3 J/g), compressive modulus (7.844 MPa, 80%), (0.273, 8–14 μm). Benefiting from the brick-like structure, which integrated insulation, absorption, reduction strategies, performance outstanding they consistent surrounding environment even when exposed source at 100 120 °C 5 min, temperatures reaching equilibrium maintained only 30.9 33.8 °C, respectively. remarkable long-term use also confirmed Comsol transfer simulation. Furthermore, possess EMI shielding effect (SE), SET = 43.3 dB in X-band. Therefore, this multimodal composite expected be potential candidate field stealth.
