  • Water-based formulations
  • Coatings and films
  • Polymer modification
  • Surface functionalization
  • Advanced materials research

Reduced Graphene Oxide

Reduced graphene oxide is processed from graphene oxide and is generally selected when improved electrical conductivity is required. It can be used in conductive materials, functional coatings, antistatic formulations, sensors, and electrochemical research.

  • Conductive composites
  • Conductive coatings
  • Antistatic materials
  • Sensor materials
  • Electrochemical research

Graphene Nanoplatelets

Graphene nanoplatelets are suitable for improving the electrical, thermal, and mechanical performance of material systems. Different thicknesses, sizes, and package options support laboratory testing, formulation development, and process evaluation.

  • Plastic and resin modification
  • Thermal materials
  • Coatings and inks
  • Rubber and composite materials

Frequently Asked Questions

What is the difference between graphene oxide and reduced graphene oxide?

Graphene oxide is generally more suitable for dispersion and surface modification, while reduced graphene oxide is commonly selected when higher electrical conductivity is required.

Can graphene nanoplatelets be used in plastics and resins?

Yes. Graphene nanoplatelets are commonly evaluated for electrical, thermal, mechanical, and barrier modification in plastics, resins, rubber, coatings, and composite materials.

What is the purpose of functionalized graphene?

Functionalized graphene can improve compatibility, dispersion, and interfacial bonding within specific formulation and composite systems.

Can graphene powder be added directly to a formulation?

This depends on the product and material system. Some products can be mixed directly, while others may require pre-dispersion, ultrasonic treatment, or blending with a polymer carrier.

How should I choose the right graphene product?

Selection should be based on the application objective, substrate, dispersion medium, processing method, target loading level, required performance, and project scale.

Are different package sizes available?

Different package options are available for laboratory screening, formulation development, and process evaluation. Please refer to the individual product page for current specifications.

Can you recommend a graphene product for a specific application?

Yes. You can provide the substrate, processing method, target loading level, dispersion medium, expected quantity, and required performance so that a suitable graphene material can be evaluated.
