The exceptional properties of graphene include its ultra-high tensile strength, excellent electrical and thermal conductivity.
Graphene is suitable for a wide range of next-generation applications, especially when utilized in 'layers' with other 2D nanomaterials. It is also a fundamental structural element of Carbon Nanotubes.
High Pressure Homogenization (HPH) is gaining popularity as an effective mechanical graphene exfoliation method. Learn more below.

Challenges of Graphene production
Scalability of production without negative impact on its properties.
Low graphene yields.
The quality of graphene produced and its electrical conductivity and strength.
Some methods produce hazardous waste and poisonous gases.
Addressing Scalability
One of the key features of our high pressure Homogenizers is their ability to scale-up to higher production levels and improved product consistency.
One example is the production of large volumes of conductive Graphene ink from flake graphite solution, which undergoes high energy / high-shear in our homogenizer processing chamber ('micro channel'). The end result (after several processing cycles) is a highly concentrated graphene suspension.
Increasing Graphene yields.
The high shear process of our technology can increase Graphene yields, which may be further increased in each additional cycle through the Homogenizer.
Improving Graphene quality.
The quality and purity of graphene produced can be determined by multiple factors, not just the method of Graphite exfoliation used.
HPH can be used to create mild exfoliation conditions, and this may decrease the formation of defects.
Other factors that can have an effect on Graphene purity include the introduction of various solvents or surfactants.
Lowering Graphene Production costs.
HPH can utilize Flake Graphite - a cheap and abundant source - as the raw material for Graphene production.
Our technology is easily scalable from Lab R&D to full production volumes.
HPH does not (normally) require the use of expensive substrates during processing.
As shown in the diagram below, the solution is recycled from the outlet reservoir back into the inlet reservoir to start another cycle.
During each cycle the graphite flakes can be exfoliated via our Micro Channels technology.
Our STANSTED High Pressure Homogenizers can be a cost-effective and efficient graphene exfoliation method.
