Cross-Stacking Aligned Carbon-Nanotube Films to Tune Microwave Absorption Frequencies and Increase Absorption Intensities

Aligned carbon‐nanotube (CNT) sheets are used as building blocks to prepare light‐weight, frequency‐tunable and high‐performance microwave absorbers, and the absorption frequency can be accurately controlled by stacking them with different intersectional angles. A remarkable reflection loss of −47.6...

Description
Summary:Aligned carbon‐nanotube (CNT) sheets are used as building blocks to prepare light‐weight, frequency‐tunable and high‐performance microwave absorbers, and the absorption frequency can be accurately controlled by stacking them with different intersectional angles. A remarkable reflection loss of −47.66 dB is achieved by stacking four aligned CNT sheets with an intersectional angle of 90° between two neighboring ones. The incorporation of a second phase such as a metal and a conducting polymer greatly enhances the microwave‐absorption capability.
