Hollow fiber-supported hydrogels wit mesh-size asymmetry

摘要

Hollow fiber-supported hydrogel membranes were developed and then modified to create mesh-size asymmetry in the gel phase within the wall of the fiber. A gradient cross-linking technique was used for modification. A shell-and-tube hollow fiber module was construted consisting of a single hollow fiber inside a housing with the ends sealed with epoxy. Fluid phase resistance calculations for the hollow fiber with differnt solution flow patterns were reviewed and applied to this particular experimental arrangement.
