Fig. 7: Graphene paper laminated composites.

a−c Schematic (a) and photographs (b, c) of the laminated composites consisting of EP and GPs. d−g SEM images and schematic of the laminated composite, showing a alternatively laminated structure. h Tensile curves of the laminated composites (8%-GP/EP) and pure EP. i Comparison of tensile strength, Young’s modulus and electrical conductivity between the 8%-GP/EP composite and pure EP. All data are normalized by the properties of 8%-GP/EP composite, which shows average tensile strength, modulus, and electrical conductivity of 540 MPa, 20 GPa, and 2.9 × 10⁴ S m⁻¹, respectively. Error bars are defined as s.d. j EMI shielding properties of the 8%-GP/EP composite and pure EP in 2−18 GHz. Scale bars, 10 mm (b, c), 200 μm (d), 100 μm (e), 20 μm (f).
