AMG007a Few Layer Graphene Nanosheets

31021308-1 Graphene Nanoplatelets (T:1-2nm, Dia: 5-10μm)

With an average thickness of 1-2 nanometers, graphene nanoplatelets provide improved barrier properties that guarantee strength, security, and reliability. Their completely graphitic composition also means that they make tremendous thermal and electrical conductors. Inevitably, this makes graphene nanoplatelets a highly sought-after product that can be used in a variety of applications, including thermoset composites, natural rubber, strong adhesives, and much more. By reducing the component’s overall mass without diminishing its strong properties, graphene nanoplatelets are a cost-effective tool that can be used to enhance overall conductivity.

31021308-2 Graphene Nanoplatelets (T:1-5nm, Dia: ~5μm)

Graphene nanoplatelets that have an average thickness of 1-5 nanometers have proved their worth by displaying positive chemical properties and high electrical conductivity. While many other conductive additives sacrifice diminishing aesthetic and mechanical properties in the base resin in exchange for being highly conductive, graphene nanoplatelets have displayed immense stiffness and strength while also remaining highly conductive. This means that products using graphene nanoplatelets will neither scratch nor burn easily. For multifunctional nanoparticles that improve a variety of properties, trust graphene nanoplatelets to serve you well.

31021308-3 Graphene Nanoplatelets (T:2-10nm, Dia: 2-7μm)

Graphene nanoplatelets from ACS Material are nanoscale particles of graphite. These nanoparticles contain stacks of graphene that are between 2 and 10 nanometers thick with diameters between 2 and 7 micrometers. A close look at the nanoplatelets would show a material that looks like graphite; the only difference is that the stack size of graphene layers is very, very small. The shape and size of the platelets makes them easy to chemically modify and disperse in order to create various composite materials. The resulting composite materials—examples include plastics, polymers, rubbers, and nylons—are electrically and thermally conductive and perform more like metals. Graphene nanoplatelets also improve barrier properties and surface toughness of composites.

Graphene nanoplatelets 2-10nm in size are available from ACS Material in 50g, 500g, and 1kg packages. Industrial quantities are also available upon request. All of our advanced nanomaterials are prepared using the latest methods and conform to the most rigorous standards for purity and consistency.

Graphene nanoplatelets (2-10nm) consist of stacks of multi-layer graphene sheets in a platelet morphology with a high aspect ratio (width–to-thickness).

31021309-2 Graphene Dispersion in NMP (1mg/mL, Dia:0.5-5μm) &31021309-3 Graphene Dispersion in NMP (4mg/mL, Dia:0.5-5μm)

Taking full advantage of the many remarkable properties of graphene often calls for dispersing it into another organic media. To be effective, graphene dispersions must be at concentrations appropriate to the final application and they must remain dispersed for a reasonable amount of time, but the strong interactions between sheets of graphene make achieving effective dispersions difficult. NMP (N-methyl-2-pyrrolidone) has proven to be one of the best solvents for creating a useful, stable graphene dispersion.
