How to Choose the Right Graphene Grade

Start with the application: Batteries, conductive polymers, coatings, electronics, sensors, thermal materials, and structural composites typically need diverse forms of graphene.
Choose the material format: Nanoplatelets or powder for additive applications, or single-layer graphene or graphene oxide solutions for advanced research and liquid-processing workflows.
Review physical specifications: Compare flake size, number of layers, thickness, purity, surface area, and bulk density before choosing a grade.
Confirm processing compatibility: Determine whether the material must operate in water, solvent, resin, polymer, coating, ink, or dry powder mixing systems.
Request documentation: SDS, COA, SKU-specific specs, and any characterisation data available for procurement and lab approval.
Ask for technical support: To assist you in finding the best graphene choices, provide MKnano with your intended application, matrix, processing technique, loading level, and desired properties.
