Fig. 2: Mechanical characterization.

a–d Azimuthal scan wide-angle X-ray scattering (WAXS) patterns (for a rotating anode X-ray source) showing the full width at half maximum (FWHM) of a rGO. b MrGO. c rGO-AD. d, MrGO-AD. e, f The corresponding small-angle X-ray scattering (SAXS) patterns for rGO and MrGO-AD. g Comparison of SAXS scattering intensities for rGO and MrGO-AD. These results indicate a decrease in porosity in going from rGO to MrGO-AD. h Bar graphs comparing the porosity of rGO and MrGO-AD. i Typical tensile stress–strain curves for the investigated sheets. j Bar chart comparing the toughnesses and conductivity of the obtained sheets. k Comparison of tensile strength and toughness MrGO-AD sheet with that of other graphene-based sheets.
