Electromagnetic Function of MAX Series Materials: A Review

ABSTRACT In the new era of advanced information and intelligent technologies, electromagnetic pollution has emerged as a growing concern, creating an urgent demand for high‐performance electromagnetic wave absorbing materials. MAX series materials, thanks to their unique layered structures and tunable physicochemical properties, have gradually emerged as a promising platform for constructing efficient electromagnetic wave absorbers. This paper systematically reviews recent research progress on MAX‐based electromagnetic wave absorbing materials, with a focus on multidimensional structural design strategies and performance optimization mechanisms. Finally, the key challenges faced by MAX series materials for electromagnetic wave absorption are discussed, and a research framework of “mechanism understanding–structural design–performance prediction–functional application” is proposed, providing forward‐looking insights and a systematic roadmap for their future development.
