II. Main Features
  • Copper foam has excellent thermal conductivity, widely used for heat conduction and dissipation in motors, electrical appliances and various electronic components.
  • Copper foam has superior electrical conductivity, with applications in nickel-zinc batteries and electric double-layer capacitor electrode materials gaining significant industry attention.
  • With unique structure and human-friendly properties, copper foam is a high-quality medical filtration material and water purification filter medium.

III. Application Areas
  • Electrode Materials: The excellent electrical conductivity makes copper foam widely applicable as skeletal electrode material for new-type batteries such as nickel-zinc batteries and electric double-layer capacitors. It has been trialed and put into batch use by several manufacturers, and is expected to be promoted as a current collector for electric double-layer capacitor electrodes, with broad prospects in electrolytic recovery of copper-containing wastewater.
  • Catalysts: In many organic chemical reactions, copper foam with large specific surface area can replace punched copper plates as chemical reaction catalysts, and has achieved good application as a carrier for photocatalytic air purification.
  • Thermal Conduction Materials: Due to its excellent thermal conductivity, copper foam can be used as an efficient flame-retardant material in many overseas high-end fire-fighting equipment, especially effective in flame isolation. It can also be made into heat dissipation components for motors and electrical appliances.
  • Sound Absorption and Shielding Materials: Sound waves undergo diffuse reflection on the copper foam surface, achieving noise reduction through expansion silencing and micro-pore sound absorption. Copper’s EMI shielding performance is close to silver, making it an excellent electromagnetic shielding material.
  • Filter Materials: With excellent structural properties and human-friendly characteristics, copper foam has mature application as filter material, with promising prospects in water purification equipment.
  • Fluid Pressure Buffering Materials: Copper foam can disperse and buffer fluids, serving as an effective pressure reduction protection device for various pressure instruments.

How does the 60% porosity and 90 PPI structure of this copper foam balance its thermal and electrical conductivity for dual-use applications?

The product description highlights excellent thermal conductivity for heat dissipation and superior electrical conductivity for electrode materials. The 60% porosity with 90 PPI and ≥98% through-hole rate ensures a continuous copper network, supporting both functions. The areal density of 0.42 g/cm³ and bulk density range of 0.1–0.8 g/cm³ indicate a highly porous structure that still maintains conductivity. However, specific quantitative trade-off data is not provided.

Can this copper foam be used directly as a catalyst carrier in photocatalytic air purification without additional surface modification?

The description notes that copper foam has achieved good application as a carrier for photocatalytic air purification. It does not specify whether surface modification is needed. The large specific surface area of the foam makes it suitable, but for specific integration requirements, contact the manufacturer.

What storage or handling conditions are recommended for this copper foam to maintain its structural integrity and performance?

The product description does not provide specific storage or handling instructions. The through-hole rate of ≥98% and open-cell structure may make it susceptible to contamination. The manufacturer offers customization and technical support, so users should contact the engineering team for recommended handling and storage conditions.

Copper foam (90 PPI, 60% porosity, 0.42 g/cm³ areal density, 2 mm thickness) is evaluated for its high electrical conductivity suitable for electrode materials in nickel-zinc batteries and electric double-layer capacitors, as well as its excellent thermal conductivity for heat dissipation and flame isolation. The ≥98% through-hole rate supports sound absorption, EMI shielding, and filtration, though the slight closed-cell fraction may marginally affect precision filtration applications.

Positive

  • Superior electrical conductivity for electrodes: Copper foam exhibits superior electrical conductivity, making it suitable as a skeletal electrode material for nickel-zinc batteries and electric double-layer capacitors, with broad prospects in electrolytic recovery applications.
  • High thermal conductivity for heat dissipation: Excellent thermal conductivity enables effective heat conduction and dissipation in motors, electronics, and fire-fighting equipment, particularly for flame isolation in high-end applications.

Trade-offs

  • Slight closed-cell fraction limits precision filtration: The through-hole rate is ≥98%, meaning up to 2% of pores may be closed, which can reduce effective surface area and filtration efficiency in applications requiring maximum open porosity.
