3D carbon skeleton/MOF derivatives for efficient electromagnetic absorption and corrosion resistance

growth and pyrolysis strategy which is based on chitosan derived CS and the MOFs ZIF-8 and ZIF-67. As a result, CS/ZIF-8 600 °C demonstrates excellent EM absorption, whose minimum reflection loss is -41.85 dB with an effective absorption bandwidth of 2.56 GHz. In addition, the CS/MOF composites exhibit splendid corrosion resistance in complex environments such as neutral, acidic and alkaline.
