Hollow fibers

Nickel hollow fiber membranes were prepared by a phase inversion and a sintering method. A nickel hollow fiber support was prepared by spinning the polymer solution containing suspended nickel powders to a hollow fiber precursor which is then sintered at elevated temperature. For these hollow fiber

In this work the preparation and characterization of gas separation hollow fibers based on polyethersulfone Sumikaexcel (PES) and polyimide Matrimid 5218 (PI) blends are reported. Scanning Electron Microscopy (SEM) was used to investigate the morphological characteristics and structure of the asymme

In this work, the effects of major spinning parameters, such as: polymer concentration, air gap distance, bore fluid composition, and take-up velocity on the structure and the permeation properties of polyethersulfone-polyimide gas separation hollow fibers are discussed in detail. It is shown that a
