Cover Story: Ni-MOF, as a metal–organic framework, has the advantages of morphology diversity and adjustable composition, which make its derivatives attractive for electromagnetic wave absorption. Herein, ternary Ni@C/PPy composites based on Ni-MOF derivatives were synthesized by coupling magnetic Ni@C nanoparticles with a conductive polymer PPy matrix through a self-assembly method. Ni@C nanoparticles are formed after Ni-MOF pyrolysis, and PPy serves as the backbone to effectively assemble and support the Ni@C nanoparticles. As a result, the optimum sample exhibited excellent performance with a reflection loss value of −50.65 dB at a filling ratio of 15 wt% under a thickness of 2.5 mm. It provides a research idea for developing microwave-absorbing materials at a low filling ratio. View this paper
