摘要： A flexible porous metal foil sheet made of a metal porous material which use a solid solution alloy, a metal element of a face-centered cubic structure or a metal element of a body-centered cubic structure as the matrix phase, wherein the thickness of the sheet is greater than 200 μm and less than or equal to 1500 μm, the average aperture is 0.05˜100 μm, and the porosity is 15%˜70%. The method for making the flexible porous metal foil comprises: (1) making viscous suspension or muddy paste of raw material powder that will form the metal porous material using a dispersing agent and a binding agent; (2) injecting the suspension or paste into a mold for making membrane, and drying the suspension or paste to form a homogeneous membrane; (3) pressing the membrane to improve the stacking density of the powder particles; and (4) sintering the pressed membrane to obtain the flexible porous metal foil. The flexible porous metal foil has more uniform aperture distribution, and better flatness of the foil.
