ACS Omega, Journal Year: 2025, Volume and Issue: unknown

Published: March 13, 2025

Composites consisting of silicone rubber and conductive fillers are extensively utilized in electronic devices due to their high performance the field electromagnetic interference (EMI) shielding. Traditional shielding polymer composites often use metal such as silver, which suffer from drawbacks costs increased density. This study details synthesis silver-coated glass microspheres (Ag@GMs) via an ethylene glycol activation method, followed by application formulation lightweight, flexible, effective EMI composites. The deposition a silver coating on surface promotes constitution three-dimensional networks, achieving maximum density 1.83 g/cm3 electrical conductivity 204.63 S/cm. At core-shell interface microspheres, polarization loss internal reflection waves significantly enhanced, resulting efficiency up 120 dB. Moreover, composite exhibits excellent bending resistance aging stability, indicating its promising potential for protection wearable, smart, precision applications.

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
