Interfacial Confinement Derived High‐Strength MXene@Graphene Oxide Core‐Shell Fibers for Electromagnetic Wave Regulation, Thermochromic Alerts, and Visible Camouflage

. Furthermore, fiber-woven textiles not only offer excellent electromagnetic interference shielding performance but also achieve quantitative regulation of electromagnetic wave transmission by adjusting the angle of the double-layered textiles. The textiles can combine with thermochromic coatings for thermotherapy alerts, visual thermochromic warnings, and visible camouflage.
