Estrutura e graus

Grafeno · Uma folha de carbono de um átomo: Nobel, hype em compósitos, poucos usos honestos.

What holds Grafeno 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.

Fases

C (honeycomb monolayer)

Chemistry

Grafeno is specified as C (honeycomb monolayer). Density band areal mass ~0.77 mg/m².

Microstructure

Order

Processing sets grain, crystallinity or fibre orientation — the reason two lots of Grafeno can test differently.

Interfaces

Surfaces

Coatings, oxide films, sizings or paper faces often decide weather and fire behaviour more than the bulk brochure.

Defects

Flaws

Inclusions, voids, knots, pinholes or residual stress start the failures that mill certificates do not list.

Grades

Variants

Grafeno is a family. Grade names below are the ones buyers actually write on RFQs.

Ageing

Time

Moisture, UV, creep, hydrogen or carbonation shift properties in service. Design to the aged state.

Ligações

Primary bonding

Grafeno holds together by ionic/covalent networks.

Secondary forces

Hydrogen bonds, van der Waals stacks or grain-boundary cohesion set toughness and moisture uptake.

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.
