Nano-Micro Letters, Год журнала: 2024, Номер 16(1)

Опубликована: Июнь 11, 2024

Two-dimensional carbon-based materials have shown promising electromagnetic wave absorption capabilities in mid- and high-frequency ranges, but face challenges low-frequency due to limited control over polarization response mechanisms ambiguous resonance behavior. In this study, we propose a novel approach enhance efficiency aligned three-dimensional (3D) MXene/CNF (cellulose nanofibers) cavities by modifying properties manipulating the 3D MXene architecture. This controlled mechanism results significant shift of main region from X-band S-band, leading remarkable reflection loss value - 47.9 dB range. Furthermore, our findings revealed importance oriented coupling influencing microwave properties. The present study inspired us develop generic strategy for tuned absence magnetic element participation, while orientation-induced derived are key controlling factors method.
