Hierarchical Ti3C2Tx@ZnO Hollow Spheres with Excellent Microwave Absorption Inspired by the Visual Phenomenon of Eyeless Urchins
文献摘要:
Ingenious microstructure design and rational composition selection are effective approaches to realize high-performance microwave absorbers,and the advancement of biomimetic manufacturing provides a new strategy.In nature,urchins are the animals without eyes but can"see",because their special structure composed of regular spines and spherical photosensitive bodies"amplifies"the light-receiving ability.Herein,inspired by the above phenomenon,the biomimetic urchin-like Ti3C2Tx@ZnO hollow microspheres are rationally designed and fabri-cated,in which ZnO nanoarrays(length:-2.3 μm,diameter:~100 nm)as the urchin spines are evenly grafted onto the surface of the Ti3C2Tx hollow spheres(diameter:~4.2 μm)as the urchin spherical photosensitive bodies.The construction of gradient impedance and hierarchical hetero-structures enhance the attenuation of incident electromagnetic waves.And the EMW loss behavior is further revealed by limited integral simulation calculations,which fully highlights the advantages of the urchin-like architecture.As a result,the Ti3C2Tx@ZnO hollow spheres deliver a strong reflection loss of-57.4 dB and broad effective absorption bandwidth of 6.56 GHz,superior to similar absorbents.This work provides a new biomimetic strategy for the design and manufacturing of advanced microwave absorbers.
