Molecular weight cut-offs and pore

The spim hoUow fibers were characterized with regard to cross-sectional membrane morphology, membrane surface chemistry, mechanical properties, water permeation, molecular weight cut-off, and pore size distribution. It was observed that the water permeation and molecular weight cut-off of the as-spim hoUow fibers are dependent on the structure of the additives.
