Graphene Foam for Sale – Professional Material Introduction
Graphene foam for sale refers to commercially available, threedimensional (3D) graphene architectures engineered for highperformance thermal, electrical, mechanical, and electrochemical applications. As an advanced nanomaterial, graphene foam combines the extraordinary intrinsic properties of graphene with a porous, interconnected, ultralight framework, making it ideal for nextgeneration batteries, sensors, thermal interface materials, composites, and electromagnetic shielding. The growing availability of graphene foam in research and industry reflects rapid advances in scalable synthesis, structural engineering, and applicationdriven customization.
1. Concept of Graphene Foam
Graphene foam is a3D porous network composed of interconnected graphene sheets with extremely high surface area, low density, and excellent conductivity. Unlike conventional bulk graphene powder, graphene foam retains continuous electrical pathways and mechanical integrity due to its monolithic structure. The foam typically possesses porosity levels above95%, densities as low as5–20 mg/cm³, and large specific surface areas reaching several hundred m²/g.
Commercial “graphene foam for sale” is typically offered in fixed dimensions, customizable shapes, and tunable pore sizes to meet the needs of academic laboratories, electronics manufacturers, and energystorage developers.
2. Structural Characteristics
Graphene foam exhibits a unique multiscale architecture composed of:
• Interconnected Graphene Network
The foam consists of a seamless, conductive lattice of fewlayer graphene sheets grown or deposited onto a 3D template.
• Tunable Pore Structure
Pores range fromtens to hundreds of micrometers, depending on synthesis method. Controlled porosity ensures optimal mass and heat transfer.
• Lightweight skeletal framework
Its ultralow density enables flexible handling, integration into composites, or direct incorporation into devices.
• High Mechanical Resilience
Despite being lightweight, the foam displays excellent compressive strength and elastic recovery due to its cellular architecture.
• HighPurity Carbon Composition
Commercial products often exceed99% carbon purity, minimizing defects and ensuring reliable performance.
3. Material Properties
Graphene foam demonstrates several exceptional characteristics:
• Superior Electrical Conductivity
Continuous graphene pathways enable fast electron transport, ideal for electrodes and conductive frameworks.
• High Thermal Conductivity
The foam structure rapidly dissipates heat, making it suitable for heat spreaders and thermal management systems.
• Large Specific Surface Area
The high surface area promotes rapid electrochemical reactions or effective adsorption of molecules.
• Chemical and Thermal Stability
Graphene foam resists oxidation at moderate temperatures, and remains stable in various chemical environments.
• Mechanical Robustness
The foam withstands repeated compression cycles and maintains structural integrity, critical for flexible and wearable electronics.
4. Manufacturing Processes
Commercial graphene foam is produced through several scalable fabrication methods:
• Chemical Vapor Deposition (CVD)
Graphene is grown directly on nickel or copper foam templates, which are later etched away to yield freestanding graphene foam. This process offers the highest conductivity and structural quality.
• PolymerDerived Carbonization
Polymeric foams coated with graphene oxide are carbonized to form conductive 3D graphene networks.
• FreezeDrying and SelfAssembly
Graphene oxide dispersions form aerogeltype foams via freezedrying and thermal reduction, allowing precise control over pore size.
• 3D Printing and Additive Manufacturing
Emerging techniques allow the direct printing of graphenebased inks into designed foam architectures.
Commercial suppliers often classify “graphene foam for sale” based on thickness, pore size, conductivity, and purity.
