MIEC hollow fiber membranes

Engineering Aspects of MIEC Hollow Fiber Membranes for Oxygen Production... 

The MIEC hollow fiber membranes are usually fabricated by a combined phase inversion and sintering process. The immersion induced phase inversion technique has been widely employed to prepare polymeric hollow fiber membranes. Due to the excellent binding capability of the polymers, a large amount of fine inorganic powder can be mixed inside the polymer solution to form a uniform mixture from which the ceramic hollow fiber precusors can be extruded at room temperature. Subsequent sintering would convert these precursor fibers into the ceramic hollow fiber membrane products. Figure...

The phase inversion/sintering technique has to be further improved to produce in a large scale MIEC hollow fiber membranes with constant macrostructure and performances so as to reduce the membrane costs.
