Electromagnetic interference shielding based on highly flexible and conductive graphene laminate

The potential of highly flexible and conductive graphene laminate is extended to the application of electromagnetic interference shielding. Graphene nanoflake‐based conductive ink is printed on paper, and compressed to form a graphene laminate with a conductivity of 0.43 × 10 5 S/m. The shielding effectiveness is experimentally measured to be above 32 dB between 12 and 18 GHz, even though the thickness of the graphene laminate is only 7.7 µm. It is demonstrated that graphene has great potential in offering lightweight, low‐cost, flexible and environmentally‐friendly shielding materials.
