- Long and narrow slit-shaped pores are predicted to have enhanced permeation and selectivity. However, it remains an unsolved challenge for the massive production of slit-shaped pores with sub-100 nm pore widths. We report, for the first time, the efficient production of membranes containing densely packed slitted pores with pore width < 15 nm from block copolymers (BCPs). Such membranes exhibit sharp selectivity and water flux 10-100 times higher than commercial membranes.
