Abstract

original image

Stimuli-responsive nanofluidic systems in room temperature ionic liquids (RTILs). The nanofluidic device can withstand high temperatures up to 200 °C, in which conventional water-based smart materials and nanodevices are invalid. The smart nanopores can be “irreversibly” turned off above the transition temperature of ca. 120–150 °C, actuated by the conformational change of the chemically-modified polymer brushes.
