C (honeycomb monolayer)
ChemistryGraphen is specified as C (honeycomb monolayer). Density band areal mass ~0.77 mg/m².
What holds Graphen together is not the nickname. Formula C (honeycomb monolayer), density areal mass ~0.77 mg/m².
Meters are atlas-relative. Grades are the SKUs buyers write.
Phasen
Microstructure
OrderProcessing sets grain, crystallinity or fibre orientation — the reason two lots of Graphen can test differently.
Interfaces
SurfacesCoatings, oxide films, sizings or paper faces often decide weather and fire behaviour more than the bulk brochure.
Defects
FlawsInclusions, voids, knots, pinholes or residual stress start the failures that mill certificates do not list.
Grades
VariantsGraphen is a family. Grade names below are the ones buyers actually write on RFQs.
Ageing
TimeMoisture, UV, creep, hydrogen or carbonation shift properties in service. Design to the aged state.

Composites & fills
Fillers, fibres, plasticisers or aggregates are part of the real product, not impurities.
Environment film
Oxides, chars, sizings or paints are the layer the world actually meets.
Change the grade, the coating or the moisture and you have a different material with the same English name.
