Abstract

Abstract Traditional microwaves absorption materials (MAMs) are applied in the form of coatings, generally inflexible, with high production costs and poor adaptability to applications in different locations. The diversification of application scenarios requires materials with multifunctionalities, but it is extremely challenging to integrate multifunctionalities within single material at present. Herein, a multifunctional CoNC@GN/PCL/TPU MAMs is synthesized. The CoNC@GN nano‐micro absorber has high‐efficiency microwave absorption ability. The electromagnetic microwave absorption performance is ultra‐light (4 wt.%), ultra‐thin (2.3 mm), and broadband (6.21 GHz), which is better than similar MAMs. Additionally,…
