Description
Summary:We report a smart polymer membrane whose pore can be switched between the "closed" and "open" state just by passing CO 2 and Ar in solution respectively. Compared with other stimuli, such as pH or temperature change, gas is an environmentally friendly and cost-effective stimulus for reversibly tuning the pore size and imparting the size selectivity of the membrane. A novel type of CO 2 -responsive polymer membrane shows gas-tunable pore size that can be used for size exclusion-based filtration of gold nanoparticles.
