Optimization of formation process in development of high performance of asymmetric membranes

Selectivity and permeability of asymmetric membrane characterize its performance for gas separation process. Unfortunately, there is usually a trade-off between permeability and selectivity thus representing one of the major obstacles to commercial application and production of membranes. Hence seri...

Optimization of formation process in development of high performance of asymmetric membranes
description Selectivity and permeability of asymmetric membrane characterize its performance for gas separation process. Unfortunately, there is usually a trade-off between permeability and selectivity thus representing one of the major obstacles to commercial application and production of membranes. Hence serious compromises are required to achieve a defect-free skin layer with minimum thickness in order to avoid dramatic loss in the overall membrane selectivity by maintaining sufficient permeability.
