[en] Through a hole in a poly(ethyl acrylate) (PEA) layer that is electrochemically grafted to the surface of a vitreous carbon electrode-that is the route that must be taken by a growing polypyrrole nanowire in the electropolymerization of pyrrole. Chain growth is controlled by diffusion of the monomer through the DMF-swollen PEA layer, which acts as a template for the formation of nanowires (shown in the picture) with diameters of 400-1000 nm and lengths of up to 300 m.
