Graphene Standard:ISO80004-13 ST

Definition of graphene:Single layer can be called graphene

Few layers of graphene materials:Below 5 layers

Multilayer graphene material:Below 10 floors

→ Single layer Graphene is in the form of a single layer of atoms in a two-dimensional hexagonal lattice

→ Spread out multi-wall or single-wall carbon nanotube can form multi-layer or single-layer Graphene

→ Single layer graphene is the basic structure of all carbon materials

→ Folding single layer graphene into a ball:  Buckyball




Characteristics and structure of graphene

■ Most of so called ‘Graphene’ in the market is not real graphene, just some kind of aggregation of graphene precursor materials.

■ Amazing Instant Graphene (AIG)

The most difficult bottleneck of graphene technology is dispersion. There are Van der Waals force to let nano graphene integrated together.

→ For example, 50 years ago the milk powder is very difficult to disperse in hot water. New invented ‘Instant Milk’ can easily disperse in hot water.

ACOOL AIG Graphene is pre-dispersed, it can be easily dispersed in Organic or Inorganic materials. ACOOL AIG graphene already be applied in many application fields.
