Figure 8. X-ray diffraction patterns and typical mechanical measurements under tensile loading of GO and graphene fibres.

X-ray diffraction patterns (a) and typical mechanical measurements under tensile loading (b) of GO and graphene fibres. The number 1 and 2 denote graphene and GO fibres, respectively. The strain rate is 5% min⁻¹. The Young's moduli of GO and graphene fibres at low deformation are about 5.4 and 7.7 GPa, respectively.
