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.

Abstract With the increasing demand for terahertz (THz) technology in security inspection, medical imaging, and flexible electronics, there is a significant need stretchable transparent THz electromagnetic interference (EMI) shielding materials. Existing EMI materials, like opaque metals carbon-based films, face challenges achieving both high transparency efficiency (SE). Here, wrinkled structure strategy was proposed to construct ultra-thin, stretchable, MXene which possesses isotropous wrinkles (height about 50 nm) periodic 500 nm). Compared flat film, film (8 demonstrates remarkable 36.5% increase SE within band. The exhibits an of 21.1 dB at thickness 100 nm, average SE/t 700 μm −1 over 0.1–10 THz. Theoretical calculations suggest that enhances film's conductivity surface plasmon resonances, resulting improved wave absorption. Additionally, films' stretchability stability. After bending stretching (at 30% strain) cycles, transmittance only 0.5% 2.4%, respectively. outstanding performances make it promising materials future smart windows wearable electronics.
