Ti3C2Tx MXene is a potential microwave absorption material due to its unique physical and chemical properties. However, the impedance mismatch of results in low absorption. In this work, 2D/2D MXene@TiO2 composites were synthesized via simple hydrothermal oxidation method, TiO2 derived situ from without adding any additional Ti precursors. with permittivity can effectively regulate matching enhance loss mechanisms. The MXene@TiO2-6 h composite shows reflection (RL) −58.3 dB at 11.36 GHz thickness 1.75 mm, maximum effective bandwidth (EAB) 4.08 (13.92–18 GHz) 1.26 mm. Furthermore, obtain efficient different frequencies by adjusting thickness; RL reach −39.1 5.04 3.5 radar cross section (RCS) lower than −19 m2 −60–60°, minimum RCS −56 15°. This work provides valuable experience developing materials.

Abstract Freeze casting is a solidification technique utilized in the fabrication of porous materials. However, freeze process quite complex, and significant challenges remain precisely controlling pore size shape structures. This study aims to investigate customization multifunctional electromagnetic wave (EMW) absorbers with 3D structures via casting. review initially presents fundamental principles underlying examines correlation between internal external factors during preparation porosity. The emerging trends constructing novel intricate macroscopic through are subsequently outlined. Furthermore, this focuses on composites various microstructures low‐dimensional building blocks, their EMW response properties. By regulating influencing mechanisms casting, absorption materials exhibit outstanding advantages such as property manipulation, controllable structure, high porosity, specific surface area, lightweight, flexibility. These features broaden applications shielding, mechanical property, radar stealth, thermal insulation fire prevention, flexible sensors, antifreeze ability, etc. In addition, we discuss prospects high‐performance using techniques.
