Electromagnetic interference shielding with graphene composites for 5G-and-beyond communication technologies

Any working electronic device is the source of electromagnetic (EM) radiation. Device miniaturization and a consequent increase in the heat and electromagnetic (EM) wave emission in the electronic systems make the simultaneous heat management and electromagnetic interference (EMI) shielding crucially important. New research shows that the extremely high thermal conductivity of graphene and good electrical conductivity, even without the energy band-gap, make graphene promising for EMI shielding and thermal management applications.
