Abstract

The rational construction of microstructure and composition with enhanced Maxwell-Wagner-Sillars effect (MWSE) is still a challenging direction for reinforcing electromagnetic wave (EMW) absorption performance, and the related EMW attenuation mechanism has rarely been elucidated. Herein, MWSE boosted β-chitin/carbon nano-onions/Ni–P composites is prepared according to the heterointerface engineering strategy via facile layer-by-layer electrostatic assembly and electroless plating techniques. The heterogeneous interface is reinforced from the aspect of porous skeleton, nanomaterials and multilayer construction. The composites exhibit competitive EMW response mechanism between the conductive loss and the polarization/magnetic loss, as describing like the story of “The Hare and the Tortoise”. As a result, the composites not only achieve a minimum reflection loss (RLmin) of − 50.83 dB and an effective bandwidth of 6.8 GHz, but also present remarkable EMW interference shielding effectiveness of 66.66 dB. In addition, diverse functions such as good thermal insulation, infrared shielding and photothermal performance were also achieved in the hybrid composites as a result of intrinsic morphology and chemicophysics properties. Therefore, we believe that the boosted MWSE open up a novel orientation toward developing multifunctional composites with high-efficient EMW response and thermal management.


Highlights:


1 The squid pen-derived aerogel with intrinsic electropositivity is prepared to electrostatically assemble carbon nano-onion with low escape energy.
2 Under the guidance of PNM model, the interface polarization is reinforced from the aspect of porous skeleton, nanomaterials and multilayer construction.
3 Benefiting from boosted Maxwell-Wagner-Sillars effect, the aerogel and film display remarkable electromagnetic wave absorption (−50.83 dB) and electromagnetic interference shielding performance (66.66 dB), respectively.
