DOI: 10.1016/j.seppur.2021.119535
Abstract: Abstract Polymeric membranes prepared from glassy polymers suffer from a permeability-selectivity trade-off relationship. When their permeability is increased, their selectivity decreases, and vice versa. The performance of membranes during pure-gas permeation is assessed by plotting… read more here.
