Hollow Metal–Organic Framework/MXene/Nanocellulose Composite Films for Giga/Terahertz Electromagnetic Shielding and Photothermal Conversion

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

Published: April 8, 2024

Abstract With the continuous advancement of communication technology, escalating demand for electromagnetic shielding interference (EMI) materials with multifunctional and wideband EMI performance has become urgent. Controlling electrical magnetic components designing material structure have attracted extensive interest, but remain a huge challenge. Herein, we reported alternating composite films composed hollow metal–organic frameworks/layered MXene/nanocellulose (HMN) by vacuum-assisted filtration process. The HMN exhibit excellent effectiveness in GHz frequency (66.8 dB at Ka-band) THz (114.6 0.1–4.0 THz). Besides, also high reflection loss 39.7 0.7 an effective absorption bandwidth up to 2.1 THz. Moreover, show remarkable photothermal conversion performance, which can reach 104.6 °C under 2.0 Sun 235.4 0.8 W cm −2 , respectively. unique micro- macro-structural design structures will absorb more incident waves via interfacial polarization/multiple scattering produce heat energy local surface plasmon resonance effect. These features make film promising candidate advanced devices future 6G protection electronic equipment cold environments.
