3D Flake-Like Bi2Te3 with Outstanding Lightweight Electromagnetic Wave Absorption Feature

Flake-like semiconductors with strong interfacial polarization exhibit excellent electromagnetic absorption properties. To the best of the knowledge, 3D flake-like Bi2Te3 is never reported as effective MAMs (microwave absorption materials). Herein, it is first introduced the novel lightweight microwave absorption of 3D flake-like Bi2Te3 synthesized by a simple hydrothermal process. Compared with the traditional research objects, the obtained Bi2Te3 possessed prominent absorbing ability at a rather thin thickness (1.0 mm), which will draw much attention to new-materials for electromagnetic wave absorption.
