Abstract

En 中文

• Meta-Aramid microfiltration membranes were fabricated via vapor-induced phase separation. • TEG and acetone optimization yielded a uniform sponge-like pore network. • The robust, non-fluorinated membranes show extreme organic solvent stability. • Stable permeance and high particle rejection were sustained in organic media.
