Performance of a nanoarchitectured tin oxide@reduced graphene oxide composite as a shield against electromagnetic polluting radiationud

摘要

Tin oxide nanoparticles architectured with a reduced graphene oxide composite (SnO2@RGO) have been synthesised by in situ reduction of graphene oxide in the presence of stannous chloride. The microwave shielding performance of SnO2@RGO has been evaluated over the X-band (8.2-12.4 GHz) range. XRD and TEM studies show that the tin oxide nanoparticles are anchored uniformly onto the surface of the reduced graphene oxide sheets. A total electromagnetic interference shielding effectiveness in the order of 62 dB was achieved, which is more than the required values (similar to 30 dB) desired for techno-commercial applications.
