Regulating microstructure and composition by carbonizing in-situ grown metal-organic frameworks on cotton fabrics for boosting electromagnetic wave absorption

Nano Research, Journal Year: 2024, Volume and Issue: 17(8), P. 7290 - 7300

Published: June 1, 2024

Abstract High-temperature carbonized metal-organic frameworks (MOFs) derivatives have demonstrated their superiority for promising electromagnetic wave (EMW) absorbers, but they still suffer from limited EMW absorption capacity and narrow bandwidth. Considering the advantage of microstructure chemical composition regulation design absorber, hierarchical heterostructured MoS 2 /CoS -Co 3 O 4 @cabonized cotton fabric (CF) (MCC@CCF) is prepared by growing ZIF-67 MOFs onto CF surface, etching, carbonization. Aside dual loss mechanism magnetic-dielectric multicomponent MOFs, etching carbonization process can effectively introduce abundant micro-gap structure that result in better impedance matching stronger via internal reflection, doped heteroatoms (Mo, N, S) to supply additional dipolar polarization loss, numerous heterointerfaces among , CoS Co CCF produce promoted conduction interfacial loss. Thus, a minimal reflection −52.87 dB broadest effective bandwidth 6.88 GHz were achieved tunning sample thickness filler loading, showing excellent performances. This research great value guiding on based absorbing materials.
