The synergistic effect of hollow cavities and multiple hetero‐interfaces displays huge advantages in achieving lightweight high‐efficient electromagnetic wave absorption, but still confronts challenges. Herein, hierarchical Co 2 P/CoS @C@MoS composites via the self‐sacrificed strategy a subsequent hydrothermal method have been successfully synthesized. Specifically, ZIF‐67 cores first act as structural template to form core‐shell ZIF‐67@poly(cyclotriphosphazene‐co‐4,4′‐sulfonyldiphenol) (ZIF‐67@PZS) composites, which are converted into P@C shells with micro‐mesoporous characteristics because gradient stabilities preferred coordination ability. deposition MoS results phase transition (Co P→Co ), yielding formation hetero‐interfaces. Benefiting from cooperative structure, extra N,P,S‐doped sources, lattice defects/vacancies, diverse incoherent interfaces, configurations, deliver superior capability (−56.6 dB) wideband absorption bandwidth (8.96 GHz) 20 wt.% filler loading.

Abstract This work reports a gallium indium alloy (EGaIn)‐doped SiBOC ceramic that possesses unique liquid‐metal‐in‐ceramic feature. The low‐viscosity liquid nature of gallium‐based metals (Ga‐LMs) and the reactive core‐shell structure provide possibilities for phase engineering inside polymer‐derived ceramics. As demonstration, EGaIn nanoparticles (NPs) are directly mixed with UV‐curable precursor (UV‐PBS) to obtain resin suitable digital light processing 3D‐printing. After pyrolysis at 800–1200 °C, ceramics uniformly distributed NP domains (Si(GaIn)BOC) obtained. plays key role in promoting carbonization preventing crack formation during polymer‐to‐ceramic process, resulting an increase both yield mechanical strength. NPs also found have (EGaIn@(GaxIn1‐ x )2O3@SiBOC) matrix, which significantly enhances dielectric properties improves interfacial polarization. result, excellent electromagnetic wave absorption performance is achieved across C, X, Ku bands, respectively. Through rational design, novel metastructure design based on Schwarz P minimal surface proposed, exhibits ultrawide effective band extending up 11.36 GHz (within C‐Ku bands).
