Abstract
The molecular recognition ion gating membrane, which is a bio-inspired membrane comprising the copolymer of N-isopropylacrylamide and benzo[18]-crown-6-acrylamide grafted onto the surface of a porous polyethylene film, responded to both a change in temperature and a specific ion signal. The gating membrane generated similar osmotic pressures to a dialysis membrane in the closed-pore state but not in the open-pore state. An optimized membrane structure was required for controlling this phenomenon. Generation of the osmotic pressure was closely related to the ion distribution through the membrane thickness.
