Because of its excellent conductivity, it has been widely used in the electrode framework materials of new batteries such as nickel zinc batteries and electric double-layer capacitors. It can also be used as electrode material for electrolytic recovery of copper containing wastewater.(2) Catalyst. In many organic reactions, people try to directly use the copper foam with large surface area instead of punched copper plate as the catalyst for chemical reaction. Foam copper as a carrier for photocatalytic air purification has also been applied more successfully.(3) Thermal conductive materials. With excellent thermal conductivity, it is a flame retardant material with excellent performance, which is used in fire fighting equipment. Moreover, foam copper has excellent thermal conductivity and permeability, and can be made into heat dissipation materials for motors and electrical appliances.(4) Silencing and shielding materials. The sound waves diffuse on the surface of the foam copper, and the effect of silencing is achieved by expanding silencing and microporous silencing principle. The shielding property of copper is close to silver, and it is an excellent electromagnetic shielding material.(5) Filter material. The excellent structural properties and the foam metal copper products which are harmless to human body have also been successfully applied as medical filtration materials. Meanwhile, the application of foam copper in water purification devices also has a good future.(6) Fluid pressure buffer material. Foam copper dispersing and buffering the fluid makes it a pressure reducing protection device for all kinds of pressure instruments with excellent results.
