High Surface Area and Electrical Conductivity

The 3D freestanding graphene foam boasts a remarkable BET surface area of 1001500 m/g and an electrical conductivity exceeding 200 S/m. Its unique porous network is engineered to optimize material interactions, making it particularly effective for high-performance applications such as energy storage and catalysis. Researchers and industries benefit from outstanding charge transport and active material dispersion.


Exceptional Thermal and Mechanical Properties

With a compressive strength between 0.12 MPa and a Youngs modulus ranging from 130 MPa, this foam is structurally robust and retains flexibility after repeated deformations. Anisotropic thermal conductivity (5500 W/mK) ensures efficient heat transfer, crucial for advanced thermal management, electronics cooling, and EMI shielding. Its structure remains stable, even under significant thermal or mechanical stress.


Versatile Industrial and Research Applications

This graphene foam is hydrophobic, flame-resistant above 500C, and insoluble in most solvents. Its customizable size, high purity (>99%), and compatibility with established nanomaterial research standards (ISO/ASTM) allow for broad deployment in commercial, industrial, and research settings. Typical uses include supercapacitors, batteries, filtration devices, sensors, and flexible electronics.

FAQs of 3D Freestanding Graphene Foam:


Q: How is 3D Freestanding Graphene Foam manufactured?

A: This graphene foam is synthesized using chemical vapor deposition (CVD) on a removable template made from nickel, copper, or polymer. After graphene growth, the template is chemically etched away, resulting in a pure, interconnected graphene network.

Q: What are the key benefits of using graphene foam in energy storage and thermal management?

A: Graphene foams extensive surface area, high electrical and thermal conductivity, and robustness enhance charge storage in supercapacitors, improve energy density in batteries, and support efficient heat dissipation in thermal management systems.

Q: When should I choose this material over other conductive foams?

A: Choose 3D graphene foam when you require superior electrical conductivity, high thermal stability (withstanding >500C), ultra-low density, excellent flexibility, and chemical resistance for applications in sensors, EMI shielding, or next-generation energy devices.

Q: Where can I apply this foam in research or industry?

A: The foam is utilized in energy storage (supercapacitors, batteries), catalysis, filtration membranes, biosensors, flexible electronics, EMI shielding, and as thermal interface materials in electronics and aerospace applications.

Q: What is the recommended storage process to maximize shelf life?

A: Store the foam in its original, vacuum-sealed bag or box in a dry and cool environment. Avoid exposure to strong oxidizers or humid air to preserve its integrity for up to two years unopened.

Q: How does the foams high porosity and surface area benefit practical applications?

A: Its >95% porosity and large surface area (up to 1500 m/g) offer vast contact sites for chemical reactions, efficient adsorption in filters, and uniform active material loading in energy storage devices.

Q: Is the 3D graphene foam safe and compliant for research use?

A: Yes, it is non-poisonous and odorless, but should be handled as nano particulates using standard laboratory safety procedures. It complies with ISO/ASTM standards for nanomaterial research.
