Abstract

Long and narrow slit-shaped pores are predicted to have enhanced permeation and selectivity. We report, for the first time, the efficient production of membranes containing densely packed slitted pores with a pore width of <15 nm from block copolymers (BCPs). Such membranes exhibit sharp selectivity and ultrahigh water flux.
