Porous stainless steel hollow fibers with shrinkage-controlled small radial dimensions

Mixed matrix carbon stainless steel (MMCSS) hollow fibres for gas separation

“…Subsequently, stainless steel (SS) hollow fibres using micron sized SS powders have been reported [11][12][13][14]. The metallic hollow fibres were prepared by extruding a mixture of metal particles suspended in a polymer solution (generally PESf) through a spinneret which then coagulates in a phase inversion process, where water is commonly as the non-solvent phase.…”

Formation of micro-channels in ceramic membranes – Spatial structure, simulation, and potential use in water treatment

“…For the ceramic membranes made via the phase inversion and sintering method, much literature is available investigating the effects of different fabrication parameters on the range of crosssection morphologies achievable for various inorganic materials and applications [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. However, an improved understanding of the formation mechanism behind these different macro-and microstructures is still needed in order to be able to accurately control and tailor the membrane characteristics according to the application.…”

Sintering of the Immersion-Induced Porous Stainless Steel Hollow Fiber Membranes

“…So far the limited several studies on the preparation of PSS hollow fiber membranes by the phase inversion/sintering technique are mainly focused on the microstructure formation of the PSS hollow fibers during the phase inversion process. For example, Luiten-Olieman and co-workers reported the variation trend of the PSS hollow fiber microstructures with the spinning conditions and the composition of the spinning suspension [14][15][16]. We also reported the synthesis of the PSS hollow fiber membranes in spiral configurations by adding special additives in the spinning solution [18].…”

“…Compared to other methods to produce inorganic hollow fibers, the phase inversion induced hollow fiber membranes also exhibit very significant advantages over the planar or tubular ones such as low permeation resistance due to the resultant asymmetric microstructures and low fabrication costs. Furthermore, the phase inversion/sintering technique is very versatile and can be modified to synthesize porous stainless steel (PSS) hollow fiber membranes [14][15][16][17].…”
