- Abstract
Lightweight and conductive MXene/reduced graphene oxide (MX/rGO) aerogels have great potential in the field of electromagnetic interference (EMI) shielding. To achieve better EMI shielding performance, some fabrication ways and reduction methods for MX/rGO aerogels have been tried, but still far from the expectation. Herein, we develop a feasible technique to fabricate MX/rGO aerogels, i.e., unidirectional-freezing and subsequent mild chemical reduction treatment using the mixture of hydroiodic acid and acetic acid glacial. The lightweight MX/rGO hybrid aerogel with the weight ratio of MX/rGO 5:5 demonstrates superior electrical conductivity (467 S/m) and EMI shielding performance (57.67 dB). When the weight ratio of MX/rGO becomes 3:5, the EMI shielding performance reaches as high as 21,427 dB cm2 g−1, which is almost higher than the EMI shielding performance of the 3D aerogels reported by the current available literature. The MX/rGO aerogels developed in this paper shows the great application potential in protecting the wearable and intelligent devices.
