Realizing graphene's potential — improve the mechanical performance, thermal conductivity and stability, electrical conductivity, and permeation barrier properties of a range of composites and formulations.
Vor-x® graphene formulations offers the ability to break traditional design trade-offs in composite materials. One of the strongest, most thermally and electrically conductive materials known, graphene is a truly multi-functional filler. The result is improved performance and enhanced cost-effectiveness for your products.
Vorbeck has the capacity for ton-scale production of graphene. Using Vorbeck's proprietary process, we convert graphite, the same material used in pencils, to Vor-x® functionalized graphene. In Vor-x®, the graphene layers are entirely disassociated, and due to their wrinkled morphology the single sheets no longer aggregate back to the graphite structure, ensuring good dispersion and ease of handling while providing the full performance advantages of graphene.

The image to the left is a transmission electron microscope image of a Vor-x® graphene sheet, showing the material's wrinkled morphology. Scale is in nanometers (nm) = one billionth of a meter. The image to the right is an atomic force microscope image also illustrating the thin, wrinkled sheet structure of
Vor-x®. Lateral dimensions are 2 µm. Image has been colored to define the vertical scale. The height of the graphene nanosheet at the lowest point is less than 1 nm (dark colors) and this defines the thickness of a single graphene layer. Maximum height of the Vor-x® wrinkles is approximately 10 nm (light colors).
The unique surface chemistry and wrinkling in Vor-x® means that the graphene sheets do not restack. Vor-x® can be used in a variety of concentrations, adjusting suspension viscosity or powder handling properties. The surface chemistry of
Vor-x® can be altered to optimize conductivity in a given matrix or to emphasize mechanical reinforcement. Request additional information about Vor-x® >>
