New composite hollow fiber membrane for nanofiltration

Developments in Membrane Research: from Material via Process Design to Industrial Application

“…The modified preparation method for interfacial polymerisation inside hollow fibres has been published recently using N,N'-diaminopiperazine as amine component. [44] 3.1.…”

A recent progress in thin film composite membrane: A review

“…Due to this reason, research work on preparation of interfacially-synthesized PA layer onto the lumen surface of hollow fiber is rather easy to carry out and has therefore gained some attention from several research groups [30,[69][70][71]. Verissimo et al [69] previously applied an intermediate organic solvent between the aqueous amine solution and the organic acid chloride solution so as to reduce not only the pin-holes on PA layer but also create a stronger adhesion between PA layer and hollow fiber support. In 2007, Yang et al [71] adopted an easier method to remove the excess PIP solution and droplets by flushing nitrogen gas slowly through the lumen side of the fibers.…”

Formation and characterization of magnetic barium ferrite hollow fibers with low coercivity via co-electrospun

“…Especially hollow fibers, this type of morphology is of interest for the aqueous environment, the storage and controlled release of drugs [16] due to higher specific surface area. It has been reported that hollow fibers could produce a significant increase in performance in filtration compared to non-hollow fibers made by the single-jet process [9,17,18]. So we can deduce it is possible to prepare 1D barium fibers with coercivity on the order of several hundred or even less.…”
