The molecular ordering in films of the conducting polymer, polypyrrole p-toluene sulfonate, has been investigated by using electron microscopy and optical dichroism. Various morphological forms have been observed, which we propose can only develop if the polypyrrole chains can continue to grow while still attached to the work electrode. Furthermore, we suggest a model that explains the development of these new features, and which may also explain the formation of fibrillar structures in other conducting polymer systems.
