Enhancing Low-Frequency Microwave Absorption Through Structural Polarization Modulation of MXenes

Nano-Micro Letters, Journal Year: 2024, Volume and Issue: 16(1)

Published: June 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.

Porous Structure Fibers Based on Multi‐Element Heterogeneous Components for Optimized Electromagnetic Wave Absorption and Self‐Anticorrosion Performance

Small, Journal Year: 2024, Volume and Issue: 20(47)

Published: Aug. 11, 2024

Abstract The excellent performance of electromagnetic wave absorbers primarily depends on the coordination among components and rational design structure. In this study, a series porous fibers with carbon nanotubes uniformly distributed in shape pine leaves are prepared through electrospinning technique, one‐pot hydrothermal synthesis, high‐temperature catalysis method. impedance matching nanofibers structure is optimized by incorporating melamine into spinning solution, as it undergoes gas decomposition during calcination. Moreover, electronic can be modulated controlling NH 4 F content synthesis process. Ultimately, Ni/Co/CrN/CNTs‐CF specimen (P3C NiCrN12) exhibited superior performance, while achieving minimum reflection loss (RL min ) −56.18 dB at thickness 2.2 mm maximum absorption bandwidth (EAB max 5.76 GHz 2.1 mm. This study presents an innovative approach to fabricating lightweight, thin materials exceptional properties wide optimizing three key factors influencing performance.

Recently, multifunctional materials have received widespread attention from researchers. Cellulose nanofibers (CNF) is one of biomass with abundant hydroxyl groups, which shows great potential in manufacturing composite material. In this paper, a kind polyaniline@CNF/polyvinyl alcohol-H2SO4 material (PANI@CNF/PVA-H2SO4) was successfully designed by in-situ chemical polymerization conductive polyaniline (PANI) onto CNF aerogel high aspect ratio, and then coated PVA-H2SO4 gel. The has specific capacitance 502.2 F/g at scan rate 5 mV/s as supercapacitor electrode. Furthermore, when the assembled into symmetrical supercapacitor, it can still provide an energy density 11.49 W h/kg power 413.55 W/kg. Besides, as-obtained PANI@CNF/PVA-H2SO4 excellent electromagnetic shielding performance 34.75 dB X-band. addition, due to flexibility PVA, composites be further applied stress sensors detect pressure human motion signals.
