Graphene Nanoplatelets (1-5nm)
Thickness: 1-5 nm
Product Detail
ACS Material Graphene Nanoplatelets (1–5 nm) are an intermediate grade in our nanoplatelet range — thin stacks of a few-to-several graphene layers with a platelet morphology and a high aspect ratio. Each particle is about 1–5 nm thick (roughly 3–15 graphene layers) and ~5 µm wide, giving a high specific surface area (90–130 m²/g) while remaining easier to handle and disperse than the thinnest grade. They build 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 1–5 nm grade in 1 g, 5 g, and 10 g packages; larger and 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 1–5 nm grade sits in the middle of our range — a high surface area with more practical handling and dispersion than the thinnest grade. Use the interactive tool below to see how layer count, specific surface area, and typical performance trade off — and where the 1–5 nm product lands relative to our thinner 1–2 nm and thicker 2–10 nm grades.
Preparation method
Ultrasonic exfoliation method. High-intensity ultrasound peels graphite down to ultrathin few-layer platelets while preserving the layered structure of the graphite crystal, giving a small stack height (1–5 nm) and a clean, high-surface product.

The 1–5 nm grade balances a high specific surface area (90–130 m²/g) with easier handling than the thinnest 1–2 nm product, making it a versatile choice for conductive and mechanical reinforcement. Surface area is obtained by the BET method. Values are typical and may vary lot to lot — consult the SDS and TDS for the specification of a given lot.

- Aerospace and other lightweight high-performance materials
As an intermediate grade, the 1–5 nm product balances conductive performance with practical handling. Graphene nanoplatelets consist of stacks of few-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. Because the powder is very fine, dispersion quality and a suitable coupling agent strongly influence the result.
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.
