Magneto-Dielectric Synergy and Multiscale Hierarchical Structure Design Enable Flexible Multipurpose Microwave Absorption and Infrared Stealth Compatibility

Nano-Micro Letters, Год журнала: 2024, Номер 17(1)

Опубликована: Окт. 16, 2024

Developing advanced stealth devices to cope with radar-infrared (IR) fusion detection and diverse application scenarios is increasingly demanded, which faces significant challenges due conflicting microwave IR cloaking mechanisms functional integration limitations. Here, we propose a multiscale hierarchical structure design, integrating wrinkled MXene shielding layer flexible Fe

Dimensional Design of Cellulose Aerogels with Schottky Contact for Efficient Microwave Absorption

Small, Год журнала: 2025, Номер unknown

Опубликована: Фев. 5, 2025

Cellulose aerogels, as a novel class of carbon-based materials, exhibit immense potential in the field microwave absorption (MWA) due to their biocompatibility, low density, unique porous structure, and tunable architecture. However, development multi-dimensional components with specialized heterogeneous structures, which are based on cellulose remains significant challenge. This 0D/1D/3D structural configuration facilitates electromagnetic properties favorable impedance matching. The Schottky contact at ZnO/Ni interface, particular, induces strong interfacial polarization, design results multiple heterointerfaces. Density functional theory (DFT) calculations reveal that barrier causes band bending, facilitating directed migration electrons interface formation an internal electric field, thus significantly accelerating multipolar relaxation process. As anticipated, CCMC/ZnO@Ni aerogel exhibits minimum reflection loss (RLmin) value -64.0 dB 13.9 GHz thickness 2.0 mm, its effective bandwidth (EAB) reaches 4.9 GHz. work gives valuable guidance inspiration for materials composed dimensional gradient holds great application wave (EMW) attenuation.
