3D Graphene Foam (Nickel Substrate) – Product Specification

1. Product Overview

Our 3D Graphene Foam is fabricated via Chemical Vapor Deposition (CVD) technology, featuring a 3D interconnected network structure that perfectly replicates the template of metal foam. The graphene sheets form a fully integrated structure through seamless bonding, combining exceptional charge transfer capability, ultra-low density, ultra-high porosity, and large specific surface area—while retaining graphene’s inherent superior electrical, thermal, and mechanical properties.
Graphene, a novel carbon material, consists of a single layer of carbon atoms closely packed into a 2D honeycomb lattice. This unique structure endows it with outstanding performances: 100x higher carrier mobility than silicon, a tensile strength of up to 130 GPa, excellent flexibility with a stretch rate of nearly 20%, ultra-high thermal conductivity, a specific surface area of up to 2600 m²/g, and near-transparency (only 2.3% light absorption across a broad wavelength range). These properties unlock vast application potential in RF transistors, ultra-sensitive sensors, flexible transparent conductive films, high-conductivity composites, and high-performance lithium-ion batteries/capacitors.

How does the ultra-high porosity of the 3D graphene foam affect its mechanical strength for structural applications?

The foam maintains excellent mechanical processability despite its ultra-high porosity. The 3D interconnected graphene network, formed by seamless bonding of graphene sheets, provides structural integrity, enabling easy cutting, stamping, and bending without compromising the foam's shape or performance.

For thermal management, how does the 3D graphene foam's thermal conductivity compare to traditional copper or aluminum heat sinks?

The 3D graphene foam exhibits superior thermal conductivity to traditional copper and aluminum heat dissipation materials. The product specification states that its efficient heat transfer performance is explicitly better than conventional metal-based thermal management solutions, making it an ideal cooling material for high-heat-density electronics.

Can the 3D graphene foam be machined into custom shapes without damaging its graphene network?

Yes, the foam is lightweight and designed for easy machining, including cutting, stamping, and bending. The graphene sheets are bonded seamlessly into a fully integrated 3D network, so standard mechanical processing does not cause delamination or structural damage, preserving electrical and thermal continuity.

The 3D graphene foam on nickel substrate provides a seamless 3D network with high electrical and thermal conductivity, but the retained nickel may introduce metal contamination in sensitive electrochemical systems, and the 2–10 layer graphene thickness introduces batch variability.

Positive

  • Seamless 3D conductive network: The CVD-fabricated graphene foam forms a fully interconnected 3D network with seamless bonding, enabling exceptional charge transfer and high electrical conductivity ideal for electrodes in supercapacitors and batteries.
  • High thermal conductivity and light weight: The foam exhibits thermal conductivity superior to copper and aluminum while maintaining ultra-low density, making it a mechanically processable thermal management material for electronic cooling and heat exchangers.

Trade-offs

  • Nickel substrate remains in product: The nickel template substrate is not removed after CVD growth, so the final foam contains nickel metal, which may leach into electrolytes or interfere with applications requiring metal-free carbon electrodes.
  • Variable graphene layer count: The specification indicates a 2–10 layer range per batch, creating inherent variability in electrical, thermal, and mechanical properties that may affect reproducibility in sensitive sensor or device applications.

Every advanced material, component, equipment, and instrument in our catalog is backed by rigorous testing. We maintain strict internal quality management frameworks and align with CE conformity metrics to deliver transparent, reproducible performance data via our public open-science repository.
