Abstract EN
This paper explores the capability of scanning transmission electron microscopy (STEM) techniques in determining the dispersion degree of graphene layers within the carbon matrix by using simulated high-angle annular dark-field (HAADF) images.
Results ensure that unmarked graphene layers are only detectable if their orientation is parallel to the microscope beam.
Additionally, gold-marked graphene layers allow evaluating the dispersion degree in structural composites.
Moreover, electron tomography has been demonstrated to provide truthfully 3D distribution of the graphene sheets inside the matrix when an appropriate reconstruction algorithm and 2D projections including channelling effect are used.
