Graphene Nanoplatelets (2-10nm)
Thickness: 2-10 nm; True Density: 2.3g/cm3
Product Detail
ACS Material Graphene Nanoplatelets (2–10 nm) are short stacks of multi-layer graphene with a platelet morphology and a high aspect ratio — each particle is only 2–10 nm thick (roughly 6–30 graphene layers) yet 2–7 µm wide. This flat, high-surface geometry makes them easy to disperse and to chemically modify, and lets them form conductive, thermally conductive networks in plastics, polymers, rubbers, and other composite matrices at low loading. CAS No. 7782-42-5.
Graphene nanoplatelets are nanoscale particles of graphite: stacks of graphene sheets thin enough that the material behaves very differently from bulk graphite while remaining far more robust and affordable than single-layer graphene. Under a microscope a platelet still looks graphitic; the key difference is that the stack is only a few nanometers tall, so a large fraction of the carbon sits at or near a surface. That high specific surface area, combined with the platelets’ large width-to-thickness ratio, is what lets them bridge fillers and build percolating conductive pathways inside a host matrix.
Added to composites — with PPO, POM, PPS, PC, ABS, PP, PE, PS, nylon, rubbers, and many other resins — graphene nanoplatelets can raise electrical and thermal conductivity, improve barrier properties, and increase surface toughness, stiffness, and wear and corrosion resistance. ACS Material supplies the 2–10 nm grade in 50 g, 500 g, and 1 kg packages; industrial quantities are available on request. All of our nanomaterials are produced by current methods and held to rigorous standards for purity and consistency.

How thickness shapes performance
Thickness is the single most useful number on this page. Thinner stacks expose more graphene surface per gram and form conductive networks at lower loading; thicker stacks are easier to handle and disperse and are often more cost-effective for bulk mechanical reinforcement. The 2–10 nm grade sits in a practical middle ground. Use the interactive tool below to see how layer count, specific surface area, and typical performance trade off — and where the 2–10 nm product lands relative to our thinner 1–2 nm and 1–5 nm grades.
Preparation method
Interlayer cleavage method. The platelets retain the layered structure of a graphite crystal, so the product is essentially few-nanometer-tall graphite with a very small stack height.

The particle-size distribution above is measured by laser diffraction on the dry powder and reflects loosely held agglomerates of platelets, not the size of an individual sheet; the lateral size of a single platelet is 2–7 µm. Agglomerates can partially break down during compounding and dispersion, depending on shear, formulation, and surface treatment. Specific surface area is obtained from the BET method. Values are typical and may vary lot to lot — consult the SDS and TDS for the specification of a given lot.
Application fields
- Conductive & antistatic plastics and conductive rubbers
- Thermal management — thermally conductive plastics and polymer composites, thermal interface materials
- High-temperature lubricating materials
- High-performance additive for PPO, POM, PPS, PC, ABS, PP, PE, PS, nylon, and rubbers
- Mechanical reinforcement — improved tensile strength, stiffness, corrosion and abrasion resistance
- Energy & electrochemistry — electrode and catalyst-support research, sensors
As a rule of thumb, typical loadings are about 2–6 wt% for mechanical-property modification and 2–8 wt% for conductivity modification. Graphene nanoplatelets (2–10 nm) consist of stacks of multi-layer graphene sheets in a platelet morphology with a high width-to-thickness aspect ratio; their layered structure is the same as that of a graphite crystal.
Application instructions
Mix the graphene nanoplatelets with the target polymer using a two-roll mill, Banbury mixer, twin-screw extruder, or another mixer common in the plastics industry. For better dispersion of the powder in the polymer matrix, a surface modifier — such as a silane, titanate, or aluminate coupling agent — is recommended before mixing the powder with the resin.
Note: the effectiveness of modification depends strongly on the type and amount of surface modifier used. We are glad to discuss what works best for your application — please call (US) 866-227-0656.
