One Pot Synthesis of Magnetic Polypyrrole Aerogel with 1D/2D Hybrid Nanostructures for Microwave Absorption

Magneto-electric composites have become a hotspot due to their unique function and regulation mechanism. This contribution describes the one pot approach to the design and synthesis of magnetic polypyrrole aerogel with 1D/2D hybrid nanostructures. We demonstrate how microwave absorption performance for the hybrid aerogel may improve depending on magneto-electric coupling hierarchical microstructure and their phase ratio. The as-synthesized sample exhibited a minimum reﬂection loss of -42.6 dB centered at 12.5 GHz, and an eﬀective absorption bandwidth reaching 7.13 GHz at 3.3 mm. This work provides a favorable potential of the synthesis and application of high-performance lightweight structure or advanced microwave absorber.
