Top Ten Reasons to Try Graphene
Graphene is an ultra-thin layer of carbon atoms arranged in a hexagonal pattern like chicken-wire.
As a multi-functional additive, this nanomaterial has been seen to impart its unique material
properties to the materials to which it is added. Discover what graphene can do!

1. Thermal Conductivity
Graphene’s very high thermal conductivity (up to 5,300 W/(m•K)) allows for heat to be quickly spread away from a heat source.In a sheet form, graphene can be used as a thermal
spreader in mobile electronics.

2. Electrical Conductivity Graphene has amazing electrical conductivity
due to its excellent electron mobility. Graphene is not a metal, but it has a
surprisingly low electrical resistance.

When graphene was added to a
thermoplastic, a 7-8 order of magnitude
reduction in electrical resistance was
observed.www.angstronmaterials.com
3. Mechanical Enhancements Graphene has the highest intrinsic
strength of all materials (up to 130 GPa). Graphene has a platelet morphology and very high
specific surface area.

4. Process Enhancement Because of graphene’s exceptional thermal
conductivity and rheological properties, the time that it takes for materials to be processed can be reduced.
This throughput enhancement can lead to savings in production costs for injection, extrusion, and blow-molding operations.

5. Barrier Properties
Graphene is impermeable to even very small molecules such as H2O, O2, H2, and He. Graphene’s
addition to a coating
formulation dramatically improved the
coating’s barrier
properties.www.angstronmaterials.com
6. Lubricity/Tribological Enhancement When a material additive reduces the surface
coefficient of friction, it is said to positively impact the material’s tribological properties.
This reduction in friction also reduces the material’s wear rate.
In studies, graphene has been seen to lower frictional forces between
surfaces regardless of the humidity in the environment.

7. EMI Shielding
Materials that provide electromagnetic shielding will block electromagnetic fields that could harm wires or electronics.
Graphene in composites has
been seen to act as an effective EMI
shield over a variety of
conditions. www.angstronmaterials.com
8. Clarity in thin films
Even though graphene in powder form appears black, a thin film of graphene blocks only 3% of light and is transparent.Thin films of graphene are
transparent and conductive.

9. Dispersability
Compared to other nanomaterials such as carbon nanotubes, graphene more easily disperses into other materials.

powder, masterbatch
polymer pellet, conductive paste, and thermal film
forms.

10. Combinations
Graphene’s unique
properties can be delivered in combination to
the material systems to which
it is added.
