MOF@wood Derived Ultrathin Carbon Composite Film for Electromagnetic Interference Shielding with Effective Absorption and Electrothermal Management

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 34(4)

Published: Oct. 17, 2023

Abstract Recently, there has been a growing demand for ultra‐thin carbonized wood films (CWF) with high shielding efficiency (SE) to replace non‐renewable alternatives. Researchers aim enhance electromagnetic (EM) wave absorption and improve interference (EMI) SE in CWF materials reduce secondary pollution from reflected EM waves. In this work, the composite film (CWF/EP/Co) thickness of 120 µm through process hot‐pressing carbonizing soaked mixed solution water‐borne epoxy (EP) Co/Zn‐MOF (ZIF‐67/8) is obtained. The CWF/EP/Co exhibits excellent conductivity (105 S cm −1 ) demonstrates an EMI (73 dB) at 200 thickness. Remarkably, specific effectiveness (SSE/t) reached 15833.3 dB·cm 2 ·g X‐band, making it highest reported value among all wood‐derived materials. have coefficient (A) 0.4, indicating their absorbing Furthermore, effect large‐scale wallpaper (170 mm×170 mm) confirmed by finite element analysis. Additionally, good mechanical properties effective Joule heating performance. This shows promise applications such as buildings smart homes, providing warming effects.
