Abstract

Excellent microwave absorbing materials can effectively solve electromagnetic wave pollution. The regulation of electromagnetic parameters is a feasible strategy for obtaining microwave absorbers with outstanding performance. In this study, a series of alumina/carbon nanotube (Al₂O₃/CNT) composites with low density and thin thickness have been prepared by the atomic layer deposition (ALD) method. The impedance matching and attenuation constant of the Al₂O₃/CNT composites can be precisely controlled by the adjustment of Al₂O₃ deposition cycles, to obtain the excellent microwave absorption performance. The maximum reflection loss value of the Al₂O₃/CNT composite can reach −35 dB (2.5 mm). This work offers a method to prepare lightweight materials with high microwave absorbing properties.
