Multifunctional MXene/C Aerogels for Enhanced Microwave Absorption and Thermal Insulation

Nano-Micro Letters, Journal Year: 2023, Volume and Issue: 15(1)

Published: Aug. 9, 2023

Two-dimensional transition metal carbides and nitrides (MXene) have emerged as promising candidates for microwave absorption (MA) materials. However, they also some drawbacks, such poor impedance matching, high self-stacking tendency, density. To tackle these challenges, MXene nanosheets were incorporated into polyacrylonitrile (PAN) nanofibers subsequently assembled a three-dimensional (3D) network structure through PAN carbonization, yielding MXene/C aerogels. The 3D effectively extends the path of microcurrent transmission, leading to enhanced conductive loss electromagnetic (EM) waves. Moreover, aerogel's rich pore significantly improves matching while reducing density MXene-based absorbers. EM parameter analysis shows that aerogels exhibit minimum reflection (RLmin) value - 53.02 dB (f = 4.44 GHz, t 3.8 mm), an effective bandwidth (EAB) 5.3 GHz (t 2.4 mm, 7.44-12.72 GHz). Radar cross-sectional (RCS) simulations employed assess radar stealth effect aerogels, revealing maximum RCS reduction perfect electric conductor covered by aerogel reaches 12.02 m2. In addition MA performance, demonstrates good thermal insulation 5-mm-thick can generate temperature gradient over 30 °C at 82 °C. This study provides feasible design approach creating lightweight, efficient, multifunctional

Abstract MXene aerogels have shown great potential for many important functional applications, in particular electromagnetic interference (EMI) shielding. However, it has been a grand challenge to create mechanically hyperelastic, air‐stable, and durable enabling effective EMI protection at low concentrations due the difficulties achieving tailorable porous structures, excellent mechanical elasticity, desired antioxidation capabilities of air. Here, facile strategy fabricating composite by co‐assembling cellulose nanofibers during freeze‐drying followed surface encapsulation with fire‐retardant thermoplastic polyurethane (TPU) is reported. Because maximum utilization pore structures MXene, conductive loss enhanced multiple internal reflections, as‐prepared aerogel 3.14 wt% exhibits an exceptionally high shielding effectiveness 93.5 dB, ultra‐high efficiency 2977.71 dB g −1 , tripling values previous works. Owing presence hydrogen bonding TPU elastomer, hyperelastic feature additional strength, stability, superior durability, fire safety. This study provides creating multifunctional applications protection, wearable devices, thermal management, pressure sensing, intelligent monitoring.
