This study successfully prepared ZIF-67@ZIF-8@RGO/CFs (Z@R/CF) multidimensional composite materials through in-situ generation and electrostatic self-assembly methods, with structural optimization achieved via freeze-drying and high-temperature carbonization techniques. It is worth noting that for Z7@R/CF, the minimum reflection loss (RL min ) reaches − 46.7 dB at a thickness of 4.5 mm, and the maximum attenuation coefficient is 140.45. This excellent performance is attributed to the synergistic effect of multiple loss mechanisms. Additionally, the material features lightweight characteristics, providing new ideas for the development of multifunctional EMA materials. It holds broad application prospects in fields such as EM protection for electronic devices and military stealth technology.
