Abstract
A piece of flexible porous metal foil is a sheet made of porous metal material using solid solution alloy, face-centered cubic metal simple substance or body-centered cubic metal simple substance as matrix phase. The thickness of the sheet is 5 to 200 micrometers, the average aperture thereof is 0.05 to 100 micrometers, the porosity thereof is 15-70%, and the sheet is made by sintering a homogeneous film. The preparation method for the flexible porous metal foil comprises: (1) preparing thick turbid liquid with raw material powder forming the metal porous material by using dispersing agent and binding agent; (2) injecting the turbid liquid into a mold cavity of a film manufacturing fixture, and drying the turbid liquid to form a piece of homogeneous film; (3) putting the film into a sintering manufacturing fixture matching with the film in shape, then sintering the film, and taking the film out after sintering and obtaining the flexible porous metal foil. The flexible porous metal foil made by the above method can be used in many fields, and have ideal performance in flexible and chemical stability.
