Abstract
We report pristine graphene (pG) as an effective shielding material for electromagnetic interference (EMI) in electronics, and RF sensor systems. The pG was produced via a simple process of mechanical exfoliation of natural graphite. The performance of as-prepared graphene film coating alone with a thickness of 27.9μm.was evaluated in terms of shielding effectiveness (SE) and demonstrate SE ~ 22.7dB–16.7dB in 1.5GHz–10GHz frequency band. The insertion loss through the alumina substrate was subtracted from the measurement result.
