A highly retentive polyamide hollow fiber membrane prepared via controlled shrinkage

摘要

Methods for making and using polyamide hollow fiber membranes and hollow fiber membranes are described herein. The polyamide hollow fiber membrane has an isopropanol permeability of about 5 L / m ² h bar to about 150 L / m ² h bar and a particle rejection rate of about 100% for particles having a nominal diameter of about 1 nm to about 25 nm . The polyamide hollow fiber membranes described herein are particularly useful for, for example, photoresist filtration.
