Phase‐Transition Microcapacitor Network in Organohydrogel for Absorption‐Dominated Electromagnetic Interference Shielding and Multi‐Mode Intelligent Responsiveness

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Abstract Hydrogels/organohydrogels show promise for flexible, intelligent electromagnetic interference (EMI) shielding, yet simultaneously achieving absorption‐dominated shielding performance, excellent mechanical properties and multi‐mode responsiveness remains challenging. This study presents a microcapacitor network strategy as an alternative to the traditional conductive percolation EMI materials. Paraffin‐nanoclay/MXene core‐shell microspheres are uniformly integrated into hydrogel matrix via in situ polymerization, forming where microsphere shells serve capacitor plates dielectric layers, respectively. Microcurrents interfacial polarization at plates, along with dipole within layer, significantly promote EM wave attenuation (absorption coefficient >0.7). Meanwhile, abundant hydrogen bonds paraffin phase synergistically enhance strength (≈0.64 MPa) stretchability (elongation break > 1000%). Due solid‐liquid transition of microspheres, organohydrogel exhibits unique ability retain high‐temperature performance room temperature. feature enhances room‐temperature effectiveness enables responsiveness. Under same deformation mode, it programmable regulation response different external stimuli, following changes or simulating changes.

Abstract Gallium‐based liquid metals with outstanding electrical conductivity and fluidity are widely used in wearable electronics for wireless communication, human–machine interaction, smart textiles. However, their makes them easily leak from the embedded conductive circuits under repeatable stretching, mechanical damage, or exposure to acidic alkaline environments, limiting reliability practical use. Here, highly stable LM–polymer composites shown ability endure significant chemical stresses, maintaining low resistance changes ( R / 0 = 3.3 2.4) after 10 times of standard washing 24 h storage corrosive solutions. The use fluoropolymer, providing robust interfacial binding gallium oxide layer, effectively serves as a barrier layer withstand damage through synergistic effect adaptive dipole–dipole interactions among enhanced hydrophobicity. as‐prepared can be readily hot pressed onto commercial fabrics develop electronic textiles (10214 S m −1 ), high air permeability (148.6 mm s moisture (30.3 g −2 ). Taking advantage excellent stability permeability, e‐textiles demonstrated washable thermal therapy patches skin‐interfaced electrodes epidermal biopotential recording.
