摘　　要：The rational design of composition nanostructures and morphologies of the carbon-based composites materials has a significant potential for tuning electromagnetic parameters and thereby improving their performance as electromagnetic wave(EMW)absorbers.In this work,the flower-like Cu/Co-NC/MoS_(2)(NC=N-doped carbon skeleton)composites were successfully prepared by employing CuCoZn-ZIF(ZIF=zeolitic imidazolate framework)as precursor with subsequent annealing and hydrothermal technique.The unique flower-like morphology and electromagnetic synergy strategy between components enable the as-obtained Cu/Co-NC/MoS_(2)composites to exhibit outstanding microwave absorption properties.Accordingly,the minimum reflection loss of Cu/Co-NC/MoS_(2)reaches-54.36 dB at 2.7 mm.When the thickness reduces to 2.2 mm,the maximum effective absorption bandwidth can be achieved as large as 6.72 GHz.This research develops useful ideas for optimizing multicomponent microwave absorbing materials.
