Synergistic effect of graphene and carbon nanotube for high-performance electromagnetic interference shielding films

We find the synergistic effect of carbon nanotubes and graphene, and design the graphene-carbon nanotube composite films with enhanced electrical conductivity (2.74 × 105 S m−1), thermal conductivity (1154 W m−1 K−1) and electromagnetic interference shielding performance (∼60 dB at 15 μm thickness).300
