Polypyrrole films containing a variety of dopants were synthesised. Special attention was given to ensuring that all films were morphologically similar so that differences in the electronic properties of the films were more strongly associated with the intrinsic character of the dopants, in particular their electron affinity. To achieve this, dopant exchange was performed by an electrochemical process and a strong correlation was found between dopant electron affinity ( X ) and film electrical conductivity.
