Every detail matters when synthesizing thin films using electropolymerization. The final shape—and the final quality—are affected by factors like solvent, deposition rate, temperature, and pressure. This scanning electron microscopy image shows a polypyrrole film that formed in tubes roughly 100 µm in diameter when Danesh Roudini of Queen’s University in Ontario, electrochemically synthesized it on a platinum electrode.
