ASSEMBLY STRUCTURE:
The assembly structure of the material is given by the material itself (Graphene platelets) and characteristics are provided in this section and in the analytical section 1.4
RIGIDITY:
Rigidity of graphene platelets is the ability to retain the shape, without damage, when the platelets are subject to mechanical (bending) forces. Rigidity in this sense is a technical property which triggers the necessity of common methods to measure the effects of a defined force on the graphene platelets and then to interpret the corresponding results. There are currently no validated and harmonised methods and guidelines to evaluate the rigidity of the material in a scientific way. AFM-images we evaluated are showing a static state of the platelets. The images show that the platelets are partially buckled (deformed), especially at the corners or that the particles folding to a crumpled napkin like structure. From this static electron microscope images it cannot be concluded whether this deformations are reversible, which would be essential to know when the rigidity of the material should be assessed.
Supporting analytical data like AFM images are provided in Section 1.4 of the IUCLID dossier. - Fraction of constituent particles in the size range 1-100 nm:
