Ultrafast and On-Demand Oil/Water Separation Membrane
System Based on Conducting Polymer Nanotip Arrays

Ultrafast
oil/water separation based on tunable superwettability
switch remains a big challenge. Here, inspired by the ultrafast water
transport mechanism in sarracenia, we develop a micro/nanostructured
porous membrane with conducting polymer nanotip arrays through the
surface-initiated polymerizations. By modulating the height (ranging
from 49–529 nm) and redox states of nanotips, a smart reversible
superwettability switch is facile to obtain with contact angles of
water/oil arranging from 161° to about 0°. Besides, liquid
transport speed was accelerated more than 1.5 times by increasing
the nanotip length. The water flux could reach up to 50326 L m–2 h–1 (1000 times that of a typical
industrial ultrafiltration membrane). This is attributed to the stable
and continuous water film along the nanotips, which provide a lubrication
layer, leading to an increase of permeability. This work provides
significant insights into macro/nanostructured membrane design for
smart separation, blood lipid filtration, and smart nanoreactors with
high permeability.
