Copper Foam

What Is Copper Foam ?

Copper Foam (Cu foam) is a solid structure of copper with many pores. It has a strong and porous structure with a regular foam density. It is pure and clean, with no coating or crushing. It has the same purity as the original copper alloy. It consists of a copper matrix with many holes or pores. The pores can be interconnected or separate depending on the fabrication method.

The excellent properties of copper, such as high conductivity and malleability, and the advantages of foam, such as low density and high surface area, make it multifunctional and very powerful. It is used in different fields, such as energy, electronics, catalysis, and filtration.

Manufacturers can obtain copper foam with high porosity (80% to 98%) and high purity (99.9%) for experimental purposes. The pores size and sheet thickness can be adjusted to fit the task's needs. The fabrication methods include electrochemical deposition, gas foaming, powder metallurgy, and sintering.

Copper foam is cost-effective and has high conductivity compared to other metal foams. It can be used as an anode material in batteries, such as lithium-ion batteries, nickel batteries, and zinc-air batteries. It also serves as a catalyst carrier or support in various chemical reactions, such as hydrogen production, carbon dioxide reduction, and methane reforming. It can also provide electromagnetic shielding and interference reduction in electronic devices and circuits.

The high porosity and large surface-to-volume ratio enable copper foam to have high thermal and electrical conductivity. It can be utilized as electrode material in fuel cells, supercapacitors, and electric double-layer capacitors. It can also act as a heat sink or a heat exchanger in various thermal management systems. It works as an excellent flame retardant or a fire extinguisher due to its high thermal conductivity and low flammability.

It is a promising material that has many potential applications in various fields. Its unique structure and properties make it versatile and adaptable for different purposes. Its high conductivity, porosity, surface area, thermal characteristics, filtration efficiency, and safety make it an attractive choice for battery manufacturing, heat transfer, catalysis, water purification, and medical applications.

Properties of Copper Foam

• High thermal conductivity: The foam can transfer heat quickly and efficiently. This property makes it suitable for heat transfer applications in motors, electronics, and other devices. It can also act as a heat sink or a heat exchanger in various thermal management systems.
• High electrical conductivity: Copper is an excellent conductor of electricity. It is widely used in electrical applications such as batteries, electrodes, capacitors, and electrical insulation materials. It can also provide electromagnetic shielding and interference reduction in electronic devices and circuits.
• High porosity: The highly porous structure of the foam makes it lightweight and flexible for different uses. The large number of pores gives it a larger surface area, which enhances its performance in catalysis and filtration applications.
• Good mechanical properties and processability: It has good strength and durability due to its solid copper matrix. It can be processed and shaped easily due to its malleability.
• Good electromagnetic shielding and noise absorption function: It can block or reduce electromagnetic waves and noise due to its porous structure. It helps in protecting electronic devices and circuits from external interference and noise. It can improve the signal quality and performance of electronic devices and circuits.
• Corrosion resistance: It is highly resistant to corrosion. The foam sheet has a stable pH range between 4.5 and 8.5, and copper is said to resist corrosion in this pH range. The strong oxide coating on copper also helps in corrosion resistance.

Applications of Copper Foam

It is highly versatile and used for various purposes in different industries.

• Electrode material: It is the electrode frame material for new batteries, such as nickel-zinc batteries and electric double-layer capacitors. It can be used as an electrode material during the electrolysis recovery of wastewater with high copper concentrations.  
• Catalyst: It is a catalyst carrier in various chemical reactions, such as hydrogen production, carbon dioxide reduction, and methane reforming. It is also applied in air purification as a photocatalyst.
• Flame Retardant material: Copper is an excellent conductor of heat; hence it is used as a heat sink a heat exchanger in various thermal management systems. The flow flammability of copper makes it a great choice as a flame retardant material on advanced fire fighting equipment, especially as flame isolation equipment.
• Noise reduction and shielding material: Due to its conductive and porous structure, this foam can block or reduce electromagnetic waves and noise. Therefore it is used to improve the signal quality and performance of electronic devices and circuits.
• Filter material: It can be used as a filter or membrane to remove contaminants and pathogens from water. Due to its nontoxic and biocompatible nature can be used as a medical filter or a scaffold for tissue engineering and wound healing.

How to use copper foam ?

• Usage of this will be different as per the applications.
• Place the product on a clean and dry surface.
• Take out the product from the Copper Foam packaging provided by the manufacturer.
• Read the user manual carefully and follow proper instructions.

Safety Measures

• When working with copper foam, wearing heavy-duty gloves and safety goggles is important to protect the user's hands and eyes from potential injury, as the foam can be sharp.
• Work in a well-ventilated area because it may release harmful fumes when cut or machined.
• If this product comes into contact with the user's skin, wash the affected area immediately with water.
• It is a flammable material, so it should be kept away from heat and flames.
• The foam can be recycled, so it should be disposed of properly.
