Enhanced Dielectric Loss via Six‐Coordinated Er Single Atoms on Porous Carbon Nanofibers for High‐Performance Electromagnetic Wave Absorption

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 10, 2025

Abstract The metal single‐atoms (M‐SAs) have shown enhanced electromagnetic wave absorption performances. However, the relationship between their coordination number with non‐metal atoms and property is still blurry. Here, erbium (Er‐SAs) coordinated six nitrogen on one‐dimensional (1D) nitrogen‐doped hollow carbon nanofibers (HCNF‐Er) are presented for high‐performance absorption. Density functional theory (DFT) calculations experimental results reveal that Er─N 6 configuration D h symmetry significantly enhances both conduction polarization losses of HCNF support, outperforming four‐coordinated M‐SAs 4 symmetry. It also found abundant porosity increases surface area, optimizing impedance matching enhancing lightweight HCNF‐Er. Consequently, HCNF‐Er‐based film shows a wide effective bandwidth (EAB) 6.0 GHz. Furthermore, exhibits excellent flexibility, thermal insulation, mechanical strength. This study offers comprehensive optimization configurations absorption, emphasizing its potential scalable applications.

MXene Assisted Shear Thickening Fluids Reinforced Anti‐Impact Composite Aerogel with Superior Electromagnetic Shielding and Flame Retardant Performance

Small, Год журнала: 2025, Номер unknown

Опубликована: Март 26, 2025

The ubiquitous mechanical and thermal damage in extreme environments puts new demands on protective equipment. At the same time, with continuous development of electronic equipment, electromagnetic hazards information leakage risks are increasing, so equipment force/thermal/magnetic protection performance needs to be developed urgently. Herein, a shear thickened composite aerogel (MS) host-guest structure is by two-step reinforcement process involving unidirectional freeze casting ultrasonic assisted penetration thickening fluid (STF). An interweaved skeleton established introducing MXene nanosheets, thus improving stability. Moreover, MS further reinforced obtained through synergetic enhancement STF, which achieves high compressive strength (570 kPa) superior impact resistance (80% dissipation). Meanwhile, shows reliable heat insulation flame retardant ability, total release as low 4.8 kJ g-1. Furthermore, demonstrates an efficient shielding 45.5 dB at extremely load 0.43 wt%. As result, this functionally integrated proving competitive candidate for damage, threats interference complex environments.
