Hierarchical Ti 3 C 2 T x @ZnO Hollow Spheres with Excellent Microwave Absorption Inspired by the Visual Phenomenon of Eyeless Urchins

Highlights Inspired by the photoreception mechanisms of urchins, the urchin-like Ti 3 C 2 T x @ZnO hollow spheres are rationally designed as high-performance microwave absorbents by constructing ZnO nanoarrays onto the surface of Ti 3 C 2 T x hollow spheres. Both experimental and theoretical simulation results demonstrate that the microstructure of urchin-like possesses giant advantages in electromagnetic wave absorption performance, which is superior to most absorbers with similar components.
