What is Graphene on Copper Foil?
Graphene copper foil is produced by depositing graphene films onto copper foil via chemical vapour deposition. Both single-layer and multi-layer graphene can be applied to copper foil to achieve better electrical conductivity, thermal dissipation, and shielding performance. The graphene film also improves the corrosion resistance of the copper foil. They are typically used as a functional layer material(such as a thermal spreader layer, EMI shielding layer, or functional metal layer) in electronic devices, automotive applications, aerospace, and industrial equipment.
Function of Graphene on Copper Foil
Electromagnetic Shielding
Compared to standard copper foil, graphene on copper foil makes more continuous current transmission, achieving superior current distribution. This further reduces electromagnetic leakage, permitting its use in higher-frequency electromagnetic interference shielding applications. Consequently, it enhances product operational stability while delivering improved electromagnetic compatibility, thereby minimising interference with other devices within the system.
Improved Thermal Management
Compared to thermal interface materials such as thermal pads, graphene on copper foil brings rapid lateral heat dissipation, thereby enhancing the thermal efficiency of these materials. Furthermore, it prevents heat accumulation, further extending component lifespan while reducing damage and failure rates. Its application in high-value equipment minimises the substantial costs associated with maintenance and replacements necessitated by temperature fluctuations.
Surface Protection
Owing to graphene’s unique structural properties, it is less prone to oxidation than copper. It also exhibits outstanding corrosion resistance. Consequently, graphene applied to copper foil provides superior surface protection for electronic components.
Enhancing the Mechanical Properties of Copper Foil
Graphene materials exhibit superior flexibility compared to copper foil, thereby achieving greater resistance to bending stress. This reduced fatigue in bending applications, minimising maintenance and replacement requirements. It can be utilised in applications such as flexible printed circuits.
Graphene on Copper Foil VS Copper Foil
Electrical Conductivity and Thermal Conductivity
Graphene has better electrical and thermal conductivity compared to copper materials, resulting in composite properties that surpass pure copper foil. Furthermore, graphene-coated copper foil demonstrates enhanced shielding performance against high-frequency electromagnetic waves. Benefiting from its planar thermal diffusion capability, it achieves greater heat dissipation efficiency and more uniform temperature control. This enables more stable operation under high-power and high-density conditions.
Thickness
Copper foil typically has thickness approximately 12~70 micrometres , with thicker foils potentially delivering better thermal dissipation and electromagnetic shielding performance. Graphene-coated copper foil, conversely, usually measures less than 1 nanometre in thickness, occupying minimal space while maintaining consistent performance regardless of thickness. For portable devices requiring high-performance thermal management and electromagnetic shielding materials, it is an ideal choice.
Durability
On the one hand, graphene-coated copper foil is more flexible than copper foil, offering enhanced resistance to bending and folding. If you use it in flexible electronic devices, graphene-coated copper foil achieves a longer service life. On the other hand, graphene-coated copper foil has greater oxidation resistance and better corrosion resistance, providing additional surface protection.
Cost
Copper foil offers additional types such as electrolytic copper foil and rolled copper foil. Electrolytic copper foil, owing to its more straightforward processing, is a cost-effective option. Graphene-coated copper foil, however, requires copper foil as its substrate and is manufactured via chemical vapour deposition (CVD). Due to its more complex production steps and higher manufacturing costs, its initial price is often higher than that of copper foil. Nevertheless, its superior performance renders it highly cost-effective.
