Single-Step Screening of the Potential Dependence of Metal Layer Morphologies along Bipolar Electrodes

Abstract : The preparation of surface gradients is a hot topic in contemporary research. Among various physical chemistry approaches, bipolar electrochemistry allows the control of such gradients through the interfacial polarization between a conducting substrate and an electrolyte solution. Here, we report the straightforward, single‐step generation of metal composition gradients on cylindrical carbon fibers. The screening of different metal deposit morphologies, which evolve gradually along a bipolar electrode, is demonstrated with monometallic layers as well as a bimetallic composite layer based on copper and nickel.
