Poly(3,4-ethylenedioxythiophene) (PEDOT) was electropolymerized from 50 mm EDOT with 1 mm tetrabutylammonium perchlorate, and acetonitrile. Stable and controllable growth of fractal PEDOT structures was achieved by varying the parameters of the voltage-driven pulsed electropolymerization. A box-counting method was used to determine the fractal dimension fdim, allowing a distinct classification of the different structures and branching. The underlying migration-driven processes enable rapid and directed growth of complex conductive structures.
