| Summary: | Abstract Highly integrated multifunctional materials are crucial for the development of next‐generation aircraft and electronic communication devices. In this study, a novel ultra‐thin MXene film with high optical transparency and broad multispectral electromagnetic responses is first fabricated using the scanning centrifugal casting (SCC) technique. The MXene‐coated PET films significantly integrate transparency, UV‐adsorption, infrared (IR) stealth, and electromagnetic shielding from gigahertz (GHz) to terahertz (THz) frequencies together to address the diverse demands of multifunctional applications. The all‐in‐one integrated flexible films exhibit excellent optoelectronic properties (sheet resistance of 163 Ω sq−1 at 82% transparency with a figure of merit of 10.88), outstanding IR stealth (IR emissivity below 55%), and ultra‐broad electromagnetic shielding performance (shielding effectiveness of over 10 dB across GHz to THz frequencies). This remarkable performance is attributed to the intrinsic multifunctionality of MXene, ultra‐thin thickness, horizontal alignment of nanosheets, and strong interfacial interactions achieved during the SCC process. These all‐in‐one flexible MXene films exhibit great potential for applications in aircraft windows, wearable electronics, and next‐generation communication technology. |
