Experimental study demonstrates direct tracking of ion drift mobilities in PEDOT:PSS films, highlighting a straightforward approach to characterize mixed ionic-electronic transport.
Using planar junctions between the conducting polymer PEDOT:PSS and various electrolytes, it is possible to inject common ions and directly observe their transit through the film. The 1D geometry of the experiment allows a straightforward estimate of the ion drift mobilities.
