Effect of Polymer Concentration on the Structure and Performance of PEI Hollow Fiber Membrane Contactor for CO2 Stripping

A series of polyetherimide (PEI) hollow fiber membranes with various polymer concentrations (13–16 wt.%) for CO2 stripping process in membrane contactor application was fabricated via wet phase inversion method. The PEI membranes were characterized in terms of liquid entry pressure, contact angle, g...
