“…1,2 Microwave absorption (MA) materials could absorb the incident waves and subsequently dissipate them, avoiding surface reflection-induced secondary pollution, thus they have generated intensive interest in addressing the EMW pollution. 3,4 Recently, carbon-based porous materials, such as covalent organic frameworks (COFs), 5 metal-organic frameworks (MOFs), 6 carbon nanotubes (CNTs), 7 etc., have emerged as promising electromagnetic absorbers (EMAs) due to their lower mass density, stronger corrosion resistance, and better design flexibility advantages over the traditional metal-based EMAs. [8][9][10] Additionally, the presented pore structure could generate more solid-air interfaces that further facilitate the multi-reflection and dissipation of the incident EMWs.…”
