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.

e-

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.

Graphene from Angstron

Materials is available in dispersion,

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.
