Abstract
The excellent electrical and optical properties of graphene provide the possibility for its application in transparent electromagnetic shielding films. The multi-layer graphene films were designed and prepared, and the average transmittances of 1–4 layers graphene in the 3–5 μm band were 97.19%, 94.89%, 93.29%, and 91.16%, respectively. The average shielding effectiveness (SE) in the 12 GHz–18 GHz frequency band is 1.52 dB, 3.07 dB, 4.58 dB, and 5.83 dB, respectively. The direct stacking of graphene can effectively improve shielding efficiency and maintain high optical transmittance in the wide infrared spectral range. This demonstrates the high infrared transmittance of multi-layer graphene film and is a method to improve electromagnetic shielding effectiveness.
