Abstract:
The effect of different superimposed structures on the transparent electromagnetic interference (EMI) shielding performance of graphene is reported. The average optical transmittance of a graphene/quartz sample with different superimposed structures in the Vis-near-infrared spectrum (400–2400 nm) is almost the same (84%). The EMI shielding efficiency (EMI SE) of the two samples after superposition is 4.85–3.96 dB, which has been greatly improved compared to the single sample. The EMI SE of the backward superposition is 0.5–0.2 dB larger than the interval superposition. The EMI SE of the interval superposition is 0.8–0.2 dB larger than the forward superposition. The backward superposition of graphene can absorb 55% of the electromagnetic waves, reflect 10%, and only 35% of the electromagnetic waves pass. We envision that graphene can obtain high EMI SE through different superimposed structures in the theoretical research and applications.
