Advanced Materials for Tomorrow's Applications Today
XG Sciences develops and produces multifunctional materials that are based on our xGnP™ brand graphene nano-platelets. We manufacture these nano-platelets through proprietary techniques that allow us to control their size and surface characteristics.
Our graphene nano-platelets are useful as nano-additives for advanced composites, as a substrate for advanced electrical or electronic applications, as the conductive component in specialty coatings or adhesives, and as a component of e-inks or printable electronic circuits.
We have also pioneered an efficient low-cost process that allows us to uniformly decorate the surface of our graphene nano-platelets with nanoparticles from a variety of metal, metal oxide and semiconductor compositions ranging from 1 to 5 nm in diameter and at compositions up to 60 w%. This gives us the ability to tailor multi-functional materials that take advantage of exceptionally large surface area to mass ratios of active metals and metal oxides for applications such as catalysis, lithium-ion battery electrodes, supercapacitors, solar cells, and energy storage. A recent publication even demonstrates that our conductive graphene nano-platelets, surface-treated with sensitized molecules, can be used to produce highly sensitive bio-sensors.
We welcome inquiries from companies and research groups around the world.
Better Nanocomposites
Our nano-particles consist of small stacks of graphene layers that can replace carbon nanotubes, nano-clays, or other carbon compounds in many composite applications. When added in trace amounts to plastics or resins, our nanoparticles make these materials electrically or thermally conductive, and less permeable, while simultaneously improving mechanical properties like strength, stiffness, or surface toughness.
For example, when our graphene nanoparticles are added to nylon, the resulting nanocomposite is significantly less permeable to gasoline or other fuels while also dissipating static electricity. This composite is an ideal material for lining fuel tanks.
When used alone or in conjunction with carbon or glass fibers our nanoparticles enhance electrical and thermal conductivity – producing strong, lightweight composites suitable for aerospace, automotive, or electronic applications.
We deliver our products in the form most suitable for customer applications. We can deliver dry powder or solutions with carrier materials ranging from water to organic solvents. We also work with selected compounders to produce "masterbatches" of high-density mixes that are suitable for dilution at final manufacturing or compounding sites, or we can deliver custom composite mixtures to your specifications. These masterbatches are available in chemistries to match most common composite systems.
Multifunctional Materials
We can produce multifunctional materials optimized for your specific application. For example, we coat our graphite nano-platelets with nanoparticles of various atomic compositions that are sized to your specifications by both metal nanoparticle size (1-2 nm, 2-3 nm, or 4-5 nm) and nanoparticle weight percent (up to 60%):
- Precious and Noble metals (e.g. Platinum, Palladium, Gold, Ruthenium, etc.)
- Other metals, metal oxides and semiconductors (e.g., Iron, Titanium, Bismuth, Boron, Tellurium)
The underlying graphene substrate can also be sized to your specifications (1 – 25 microns) so that material handling becomes easy and suitable for your processes.
