Abstract Conductive textiles with electromagnetic interference (EMI) shielding functionality are highly desirable for growing flexibility requirements of EMI devices. Most extant coatings on rely rigid nanomaterials, which susceptible to detachment, and generate a great deal reflected EM waves. Thus, there is high demand that stretchable, stable, capable suppressing the secondary reflection toward incident Liquid metal particularly suitable candidate owing its electrical conductivity excellent conformality. Herein, straightforward coating strategy developed fast fabrication Ion/Clay‐F reinforced ionogel encapsulation. Especially, method enables direct transformation fluid‐like liquid into clay‐like state preparation sealings from monomer solutions. The resulting exhibits promising features, including total effectiveness (SE T ) (highest value 49.3 dB single layer an average 73.0 three layers), low reflectivity (0.404), improved tensile strength (13.16 MPa) tolerance in wide range temperatures (−18–100 °C). Remarkably, such outperforms pure cotton fabric terms thermal management, delivering superior heat dissipation insulation properties.
