Abstract
In this study, we report a facile method to prepare rod-like Te material, which can be used as a novel microwave absorber. Diameter of the Te rods can be tuned in the range of 46–51 nm by changing the reaction time. With the increase of Te particle diameter in the composites, the microwave absorbing property gets worse. As for the Te-0.5 sample with diameter of 45.7 nm, a maximum reflection loss value of −53.8 dB at 16.0 GHz and an effective absorption bandwidth (4.8 GHz) ranging from 13.2 to 18 GHz at the thickness of only 1.55 mm can be achieved. To the best of our knowledge, it is the first time to investigate the microwave response of Te rods. These rods show obvious potential for lightweight, highly efficient microwave absorption in high frequency.
