摘要

•3D flower-shape Co/Cu bimetallic nanocomposites were synthesized.•Nanoflower microstructure and multicomponent are conducive for improving the impedance matching.•The minimum reflection loss reaches − 51.7 dB at 12.6 GHz with a thin thickness of 2.7 mm.•The effective absorption bandwidth is as broad as 6.4 GHz (9.7–16.1 GHz) with the thickness of 2.7 mm.
