Abstract

original image

Ultrathin polyelectrolyte gel pH-responsive membranes with sub-micrometer pore size are synthesized on planar substrates. The membranes are thin porous films made of a crosslinked polyelectrolyte that can be easily transferred onto various porous and nonporous substrates for the fabrication of devices with pH-controllable permeability (see figure).
