Direct measurement of ion mobility in a conducting polymer

Adv Mater. 2013 Aug 27;25(32):4488-93. doi: 10.1002/adma.201301240. Epub 2013 Jun 20.


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.

Keywords: charge injection and transport; organic electronics; time-of-flight technique.
