Graphene Nanoplatelets, Multilayer graphene flakes

Product Information

Graphene Nanoplatelets are flakes composed of multilayer graphene sheets in a "platelet" morphology. The unique shape with a high aspect ratio of thinness to width give them excellent electrical and thermal conductivity and make them ideal for applications such as strengthening composites and matrix materials, serving as barriers. Unique features of graphene nanoplatelets benefit it greatly to gain a place in the market. ATT produces graphene nanoplatelets in multiple sizes and grades; Graphene samples are also available as nanoflakes on silicon or SiO2 substrate wafers. ATT supplies Graphene Nanoplatelet with high quantity and more types for different applications.

Graphene nanoplatelet aggregates are aggregates of sub-micron platelets with a diameter of <2 microns and a thickness of a fewnanometers, a bulk density of 0.2 to 0.4 g/cc, an oxygen content of <2 wt% and a carbon content of >98 wt%, and are ofered as blackgranules or black powder.

Applications of Graphene Nanoplatelets

Graphene nanoplatelets have a variety of applications. They are used to enhance the characteristics of a wide variety of polymeric materials, including thermoplastic and thermoset composite materials, natural or synthetic rubber, thermoplastic elastomers, lubricants, paints, and coatings, due to their special nano-scale volume, form and surface structure. The graphene nano-plates are delivered in a granular shape with the correct choice of diffusion aids, devices, and techniques in water, organic solvents, and polymers. Graphene nanoplatelets used alone can substitute traditional as well as nano-scale chemicals while extending the scope of altered properties. These are used in conjunction with other additives to reduce costs and extend the alteration of materials.

1. Improve Reliability and Thermal Conductivity

The graphene pads that make up the nanoplatelets, like all other carbon-based systems, are both thermally and electrically conductive. Nevertheless, the platelet structure, unlike nano-tubes and carbon fibers, has greater thermal touch resistance at lower load points, resulting in higher thermal conductivity than other carbon particles or fibers. Graphene nanoplatelets could be used to decrease the thermal expansion factor of most composites and to raise the intensity of maximum use. Dimensional stability and operating temperature tolerance are also improved, making polymers adjusted in thermally challenging conditions with nanoplatelets excellent for dimensional critical parts.

2. Increase in Electrical Conductivity

The graphene plates that make up these nanoplatelets are highly conductive and in most polymeric materials create an effective conductive network at low load levels. The shielding efficiency is usually attained in thermoset resins at charging rates of 2-3 wt percent and in thermoplastics at 5-7 wt percent. Furthermore, unlike so many permeable compounds, such nanoplatelets may not adversely affect the mechanical or esthetic properties of the base material, and neither are they abrasive tools as can be metal flake or fabric.

3. Reduction of Porousness

The graphene nano-platelets dramatically reduce the permeability and scattering coefficients of a composite content when compressed into a polymer film or solid component. The platelets' high aspect ratio–which is much larger than they are dense makes them efficient at low load speeds- significantly reduces costs and effects on other properties. Permeability is significantly affected by the additive's particle size, and large diameter particles typically have lower absorption reductions.

Moreover, electrical equipment are built on flexible synthetic materials. As a way to create elastic and compatible conductive materials, the combination of mechanical properties of polymers and conductive nano-fillers is exciting. However, the high price of nano-silver restricts its huge-scale production. Due to their versatility and low surface toughness, carbon-based conductive nano-fillers, and graphene nanoplatelets, in general, received greater attention as products for versatile devices.

The functionalization of stretchable thin films with Graphene nanoplatelets-based conductive ink is another exciting approach to versatile electronics. In fact, the device's sensing capacity was strengthened after the addition of graphene nanoplatelets. In contrast, Graphene nanoplatelets reduced the sample's active surface area and boosted the electron interaction between the sample and ammonia gas.

Packing of Graphene Nanoplatelets

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.
