Lightweight graphene aerogels by decoration of 1D CoNi chains and CNTs to achieve ultra-wide microwave absorption

Biao Zhao et al.

Summary: Hybrid graphene aerogels decorated with 1D CoNi chains and CNTs exhibit strong microwave absorption properties, with optimal reflection loss value of -50.8 dB and effective absorption bandwidth of 8.5 GHz. The enhanced microwave absorption is attributed to high ohmic loss, multiple polarization, and eddy current loss induced by a 3D macroscopic conductive network. The GA-CNT-CoNi aerogel is considered a promising candidate for microwave absorption due to its characteristics of ultra-low filler content, strong absorption, ultra-wideband, small thickness, and lightweight.
