Microwave-assisted ZnO-decorated carbon urchin resembling ‘shish-kebab’ morphology with self-healing and enhanced electromagnetic shielding properties

Abstract

Herein, inspired by Acacia auriculiformis fruit, the shish-kebab-like growth of ZnO on carbon urchin (ZnO@CU) was designed using microwave radiation, thus leading to a hierarchal 3D structure that can promote multiple internal reflections through polarization centers.
