Reduced Graphene Oxide

Buy Reduced Graphene Oxide for Your Application

Reduced graphene oxide is selected across research and industrial development projects where a graphene-derived material is required with a combination of electrical conductivity, carbon-based structure and residual surface functionality. The correct rGO grade depends on the application, formulation and processing conditions rather than on a single material property.

Nanografi's reduced graphene oxide category is designed to help buyers compare standard and functionalized rGO grades according to technical requirements. Available products include a 99% purity, 2-5 layer reduced graphene oxide powder and Tetraethylene Pentamine functionalized reduced graphene oxide, rGO-TEPA.

For projects requiring a liquid format rather than dry powder, a 99.5% purity reduced graphene oxide water dispersion is also available separately.

Which Reduced Graphene Oxide Should You Choose?

The first decision is whether the application requires standard rGO, chemically functionalized rGO or a ready-prepared dispersion.

These options should not be treated as different quality levels. They are different material formats designed for different processing requirements. Standard powder provides greater formulation flexibility, while functionalized rGO changes the surface chemistry and a ready-made dispersion simplifies compatible liquid-processing workflows.

Reduced Graphene Oxide, 99% Purity, 2-5 Layers

For buyers looking for a general-purpose reduced graphene oxide powder, Nanografi's standard rGO grade is specified at 99% purity, with a 2-5 layer structure and a 1-10 µm particle size.

This grade can be considered where rGO is required as a conductive or functional carbon component in:

• Battery and supercapacitor electrode development
• Conductive polymer and rubber composites
• Antistatic and electrically conductive formulations
• Sensors and biosensor research
• Functional coatings
• Hybrid nanomaterials
• Research-scale conductive inks and pastes

The product page also provides material characterization information including SEM, XRD, Raman, XPS and TEM data, allowing technical buyers to review more than the basic commercial specification before selection.

When Should You Choose Functionalized rGO?

Standard reduced graphene oxide is not always the most suitable option when interfacial chemistry is critical. In polymer systems, coatings, sensor functionalization and catalyst-support applications, surface compatibility can be as important as electrical performance.

TEPA-functionalized reduced graphene oxide introduces amine-containing functionality to the rGO surface. The current Nanografi grade is supplied in powder form with a specified average particle size of 7 µm.

rGO-TEPA can be evaluated where a formulation requires:

• Amine-containing surface groups
• Improved interaction with selected polymer systems
• Additional sites for chemical functionalization
• Surface modification for sensor development
• Integration with catalyst or nanoparticle systems
• Modified adhesion or interfacial behavior in coatings

Functionalized rGO should be selected because the surface chemistry supports the intended formulation, not simply because it is a modified version of standard rGO.

Reduced Graphene Oxide Powder or Dispersion?

For commercial and R&D buyers, the choice between powder and dispersion usually comes down to process control.

Choose rGO powder when:

• You need to determine your own concentration.
• You want to select the solvent or polymer matrix.
• The rGO will be compounded directly into a solid material.
• You need flexibility for formulation development.
• You plan to perform your own dispersion or surface treatment.

Consider an rGO dispersion when:

• Your process is already water based.
• You prefer to avoid an initial dry-powder dispersion step.
• The supplied concentration is compatible with your formulation.
• The material will be used in films, coatings or other solution-based processes.

Nanografi's Reduced Graphene Oxide Water Dispersion is supplied at 2.0 wt% rGO concentration and can be evaluated separately for liquid-processing requirements.

What Should You Check Before Buying Reduced Graphene Oxide?

Reduced graphene oxide should be purchased against application-specific technical requirements. Buyers should compare the following parameters before selecting a grade:

• Purity: Confirm the grade-specific purity rather than using a general rGO value.
• Layer count: Few-layer and more strongly stacked materials may behave differently during dispersion and film formation.
• Particle size: Particle or lateral dimensions can affect dispersion, conductive network formation and composite processing.
• Surface chemistry: Determine whether standard residual functionality or additional chemical functionalization is required.
• Physical form: Select powder or dispersion according to the production workflow.
• Matrix compatibility: Consider the polymer, solvent, resin, electrolyte or other surrounding material.
• Target function: Conductivity, reinforcement, sensing, electrochemistry and surface modification can require different rGO characteristics.

For technical purchasing decisions, the individual product specification should remain the primary reference. Properties measured in one rGO formulation or published research system should not automatically be applied to another grade.

Reduced Graphene Oxide for Composites

rGO is frequently selected as a functional additive for polymer and rubber systems where electrically conductive, antistatic or multifunctional behavior is being developed. Nanografi's standard rGO product is listed for use with polymer matrices including PPO, POM, PPS, PC, ABS, PP, PE, PS, nylon and rubbers.

The optimum concentration is formulation dependent. Dispersion quality, matrix chemistry, particle distribution and processing conditions can affect whether an electrically connected rGO network forms within the composite.

Where surface interaction with the matrix is a priority, functionalized rGO such as rGO-TEPA may be more appropriate than an unmodified grade.

Reduced Graphene Oxide for Energy Storage

Reduced graphene oxide is widely evaluated in battery and supercapacitor research as a conductive carbon component, supporting structure or part of a hybrid electrode material. Its suitability depends on the complete electrode architecture, including the active material, binder, electrolyte, porosity and rGO distribution.

For commercial material selection, buyers should focus on reproducible grade specifications and compatibility with their electrode-processing route rather than treating rGO conductivity as a universal material constant.

Reduced Graphene Oxide for Sensors and Coatings

rGO is also used in sensor and coating development where its conductive carbon network and chemically accessible surface can be incorporated into multifunctional formulations.

Standard rGO may be suitable where conductivity and general graphene-derived surface characteristics are required. Functionalized grades can be evaluated where additional chemical interaction, receptor attachment or matrix compatibility is needed.

Technical Information and Product Documentation

Material documentation is important when comparing advanced-material suppliers. Nanografi's rGO product pages provide grade-specific technical information rather than relying only on category-level descriptions.

Depending on the product, available information includes technical specifications, characterization images and MSDS documentation. The standard 99% rGO grade includes SEM, XRD, Raman, XPS and TEM characterization information, while the rGO-TEPA page provides composition and particle-size data together with SEM images.

Reviewing these product-level details helps ensure that purchasing decisions are based on the specific grade being ordered.

Reduced Graphene Oxide Quantities and Quotations

Nanografi's standard reduced graphene oxide is offered in multiple quantity options, while larger quantity requirements can be handled through a tailored quotation. Buyers planning pilot production, scale-up studies or recurring material requirements can use the Get a Quotation page to provide quantity and project requirements.

For early-stage R&D, smaller quantities can be selected directly from the relevant product page. For higher-volume purchasing, confirm the required grade, quantity and technical specifications before requesting a quotation.

Reduced Graphene Oxide vs Graphene Oxide

Buyers comparing rGO with graphene oxide should primarily consider electrical requirements and surface chemistry. Graphene oxide contains a higher concentration of oxygen-containing groups and is generally easier to process in aqueous systems, while reduction partially restores the conjugated carbon network of rGO and generally increases electrical conductivity.

The category page does not need to reproduce the full chemistry behind these materials. For a detailed technical comparison, see Nanografi's guide to reduced graphene oxide properties, synthesis and applications.
