xGnP^®® graphene nanoplatelets can be used to provide electrical conductivity in most polymeric materials. Like carbon nanotubes, the graphene sheets that form these nanoplatelets are highly conductive and form an effective conducting network at low percolation thresholds – the concentration necessary to achieve electrical conductivity. Unlike many conductive additives, xGnP^®® nanoplatelets do not negatively affect the base resin’s mechanical and aesthetic properties, nor are they abrasive to tooling as metal flake and fiber can be.

ESD and EMI/RFI shielding capabilities are typically achieved at loading levels of 2 - 3 wt% in thermoset resins and 5 -7 wt% in thermoplastics.xGnP^®® nanoplatelets typically show percolation thresholds as good as, or better than, most other carbon materials. This fact, coupled with performance advantages in areas like stiffness and toughness, makes the material an ideal additive in situations where cost-effective performance is important.

From ESD to EMI Shielding

Conductivity varies with loading in most composite matrices. xGnP^® Graphene nanoplatelets can be used to achieve levels of electrical conductivity from very low to very high. Here is an example in a control epoxy.

In thin films or coating applications, it is possible to reach electrical conductivity levels of 1,000 siemens/cm or greater. Please contact us for more information if you are interested in coatings, films, or similar applications.

Note: the properties and measurements provided on this page are shown for comparison purposes only. The actual performance of xGnP^® in a composite application will, of course, depend on matrix materials, processing, densities, and dispersion of the materials. In some cases, surface treatments or other functionalization can significantly improve results.
