Herein, an efficient approach to prepare flexible, transparent, and lightweight films based on graphene nanosheets (GNS) and silver nanowires (AgNWs) for high electromagnetic interference (EMI) shielding effectiveness (SE) has been explained. High-conductive GNS were fabricated by liquid phase stripping and composited with AgNWs by a two-step spin-coating method. Owing to the high transparency, good conductivity, and homogeneous distribution of both GNS and AgNWs, the obtained GNS/AgNWs film exhibits superb EMI SE and light transmittance, yielding a significantly high EMI SE up to 26 dB in both Ku-band and K-band and light transmittance higher than 78.4%. Moreover, this GNS/AgNWs film shows good flexibility and excellent structural stability. The obtained flexible, light and transparent film could have a great potential for transparent EMI shielding and smart electronics. (C) 2019 Science China Press. Published by Elsevier B.V.
