Abstract EN
A new alumina membrane with hour-glass shaped nanochannels is reported using the double-side anodization method and the subsequently in situ pore opening procedure, which is applied to develop the tunable ionic current rectification devices that were modulated by ions gradient.
By regulating the pH gradient, tunable ionic current rectification properties which are mainly dependent on the asymmetric surface charge density or polarity distribution on the inner walls of the nanochannels can be obtained.
The enhanced ionic current rectification properties were presented due to the synergistic effect of the voltage driven ion flow and diffusion driven ion flow with the application of pH and electrolyte concentration gradients.
Therefore, such specific alumina nanochannels would be considered as a promising candidate for building bioinspired artificial ion channel systems.
