Graphene Nanoplatelets (1-2nm)
Thickness: 1-2 nm
Product Detail
ACS Material Graphene Nanoplatelets (1–2 nm) are the thinnest grade in our nanoplatelet range — ultrathin stacks of just a few graphene layers with a platelet morphology and a very high aspect ratio. Each particle is only 1–2 nm thick (roughly 3–6 graphene layers) yet 2–3 µm wide, so an exceptionally large fraction of the carbon sits at the surface. This maximizes specific surface area and lets them build conductive, thermally conductive networks in plastics, polymers, rubbers, and other composite matrices at very 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 one or two nanometers tall — just a few atomic layers — so nearly all 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 1–2 nm grade in a 500 mg package; 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 1–2 nm grade is the thinnest we offer — highest surface area and lowest loading to reach a conductive network, at the cost of being the most delicate to disperse. Use the interactive tool below to see how layer count, specific surface area, and typical performance trade off — and where the 1–2 nm product lands relative to our thicker 1–5 nm and 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 very small stack height (1–2 nm) and a clean, high-surface product.

Because each platelet is only a few atomic layers thick, the 1–2 nm grade is expected to offer the highest surface area per gram in our nanoplatelet range, which supports conductive-network formation at very low loading. As the finest powder in the range, it benefits from careful dispersion and a coupling agent. Values are typical and may vary lot to lot — consult the SDS and TDS for the specification of a given lot.
Application fields

- Mechanical reinforcement — improved strength and stiffness at low loading
- Electronics & basic research — graphene transistors, electronic chips, antenna materials
- Aerospace and other lightweight high-performance materials
As the thinnest grade, the 1–2 nm product reaches conductive performance at low loading. 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) (888)-742-0534.
