摘要

The ionic concentration variation arising in overlapped electric double layers in nanochannels presents different electrokinetic behaviour from that in microchannels. Using a modified concentration approach, the results reveal that the surface charge density is insensitive to the concentration in the low-salt regime, and a nearly constant streaming conductance is predicted. A scaling analysis confirms that the streaming potential also has a constant value because of length scale effects, but not due to the accumulated charge in the double layer.
