Developing lightweight polymer shielding membranes with additional physicochemical properties is of great significance for addressing the complex contemporary security demands. However, precise structural design at molecular level remains a challenge. Herein, unique Janus composite membrane assembled from conductive AgNWs/MXene 1D/2D network and polyurethane elastomer (MPHEA), displaying combined superior electromagnetic effectiveness (EMSE) up to 80 dB remarkable infrared stealth capability wide temperature range room 50 °C. Moreover, endowed chemical crosslinking in resulted exceptional mechanical strength, self-healing, adhesion. The maintained (over 20 dB) even under strain 40% recovered efficiency 90% after damage self-healing are observed, which attributed synergistic 3D elastic multi-dimensional crosslinked MPHEA@AgNWs/MXene membrane. This work has represented an excellent micro-nano structure strategy on multifunctional wave manager application scenario.

Abstract The flexible manipulation of the position and type metal cations in spinel ferrites gives possibility tuning its dielectric magnetic properties, thus opening up broad design space for broadband low‐frequency absorption. However, there are still challenges how to ensure that diverse designs can be effectively introduced into ferrite lattice form homogeneous entropy‐stable compounds, further engender stable compounds with special multi‐interface hollow micro‐nano structures achieve lightweight efficient performance. In this paper, opened‐hollow multi‐shell high‐entropy (FeCoNiZnMg)Fe 2 O 4 @C microspheres a controllable carbon‐coated triple‐shell composition constructed. designed structure enhances interactions between shells regulates domain effective fields. an incredibly high absorption strengths (−60.5 dB) wide (9.3 GHz). Meanwhile, entropy effect adjusts anisotropic field size, significantly improving 4–8 GH band, far exceeding performance ferrite@C materials without forming phase. This unique composite based on strategy offers exciting prospects rational accurate construction polarization design.
