TL;DR: Anion exchange experiments performed on electrochemically prepared thin films of polypyrrole/ClO/sub 4/sup -/ demonstrate that the anions are not tightly bound to the polymer matrix.
Abstract: Anion-exchange experiments performed on electrochemically prepared thin films of polypyrrole/ClO/sub 4//sup -/ demonstrate that the anions are not tightly bound to the polymer matrix. Auger electron spectroscopy reveals that ClO/sub 4//sup -/ can be replaced by a number of different anions. In addition, certain anions will not replace ClO/sub 4//sup -/ while others will induce only partial replacement. The relevance of entropic and steric factors is discussed in relationship to the exchange process.
