Mxene Based Aerogel Composite with Thermal Camouflage and Electromagnetic Wave Absorption Performance

Abstract

In this study, the electrospinning method was successfully applied to the preparation of Ti3C2@Fe3O4@rGO aerogel. To accomplish comprehensive advantages, reduced graphene (rGO), Ti3C2 MXene nanosheets and Fe3O4 nanoparticles were suitably combined. The prepared Ti3C2@Fe3O4@rGO nanomaterials with superior high-temperature indoor/outdoor thermal camouflage performance: wide camouflage temperature range (from room temperature to over 200 ℃), large reduction in radiation temperature (exceeding 120 ℃ for objects with temperatures over 200 ℃), and high electromagnetic interference shielding efficiency. In conclusion, the successful preparation of Ti3C2@Fe3O4@rGO provides an effective strategy for the design of high-temperature thermal camouflage and microwave absorber in the future.
