MXene based aerogel composite with thermal camouflage and electromagnetic wave absorption performance

In this study, the electrospinning method was successfully applied to the preparation of Ti3C2 @Fe3O4 @rGO aerogel. To accomplish comprehensive advantages, reduced graphene oxide (rGO), Ti3C2 MXene nanosheets and Fe3O4 nanoparticles were suitably combined. The prepared Ti3C2 @Fe3O4 @rGO aerogel 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 ℃). Meanwhile, the electromagnetic interference (EMI) shielding efficiency of the Ti3C2 @Fe3O4 @rGO in the X-band reaches 50 dB which means that it can shield more than 99.9 % of the incident electromagnetic waves. 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.
