Abstract

Recent progress in ionic rectifier technology suggests that elementary devices based on microholes (5 to 40 μm diameter in 5 μm thick poly-ethylene-terephthalate or PET) are feasible based on, for example, highly conducting ionomers such as Nafion®. The main component to consider is the ionic diode (as "cationic diode" or "anionc diode"). The mechanism for the rectification effect can be traced back to a combination of ionomer conductivity (in the "open diode" state) and geometry-induced concentration polarization (in the "closed diode" state). This report describes state-of-the-art devices and it explores potential for applications of ionic rectifiers in water purification.
