Hydro/Organo/Ionogels: “Controllable” Electromagnetic Wave Absorbers

Advanced Materials, Journal Year: 2022, Volume and Issue: 34(43)

Published: Sept. 6, 2022

Demand for electromagnetic wave (EMW) absorbers continues to increase with technological advances in wearable electronics and military applications. In this study, a new strategy overcome the drawbacks of current by employing co-contribution functional polymer frameworks liquids strong EMW absorption properties is proposed. Strongly polar water, dimethyl sulfoxide/water mixtures, highly conductive 1-ethyl-3-methylimidazolium ethyl sulfate ([EMI][ES]) are immobilized dielectrically inert networks form different classes gels (hydrogels, organogels, ionogels). These demonstrate high correlation between their dielectric polarity/ionic conductivity/non-covalent interaction liquids. Thus, performances can be precisely tuned over wide range due diversity stability The prepared hydrogels show good shielding performance (shielding efficiency > 20 dB) constants, while organogels moderate attenuation ability impedance matching achieve full-wave X-band (8.2-12.4 GHz) at 2.5 ± 0.5 mm. ionogels also offer effective bandwidth (10.79-16.38 GHz 2.2 mm) via prominent ionic conduction loss. short, work provides conceptually novel platform develop high-efficient, customizable, low-cost absorbers.
