摘要： The present invention discloses a Fe—Al-based metal porous membrane and a preparation method thereof, which relate to the technical field of industrial gas-solid and liquid-solid separation and purification, and mainly address problems in the prior art, such as cracking-prone and peeling of a membrane layer of an existing Fe—Al-based metal porous membrane during its preparation and use. The preparation method of the present invention comprises the steps of: adding a Fe—Al-based metal powder and a metal fiber powder into an organic-additive-added water-based solvent, and mixing them into a slurry; casting the slurry, through a casting machine, to form a membrane green body on a metal substrate layer, and letting it dry; and placing the dried membrane green body in a sintering furnace, to remove organic substances and perform high-temperature sintering and predetermined-temperature reaction synthesis.

摘要： A method for producing a microstructured air-permeable environmental barrier membrane includes providing a substrate, and structuring a through hole into the substrate, the through hole extending fully through the substrate between two opposite surfaces of the substrate, leaving the through hole uncovered, and depositing one or more nanofibers onto at least one of the two opposite substrate surfaces by applying at least one of an electrospinning or blowspinning method, such that the spun nanofibers combine to a network of nanofibers that forms a free-standing and mechanically compliant nanofibrous membrane covering the previously uncovered through hole.
