Abstract
A simple two‐step electrochemical method is proposed for the synthesis of nanowire‐based polypyrrole hierarchical structures. In the first step, microstructured polypyrrole films are prepared by electropolymerization. Then, polypyrrole nanowires are electrodeposited on the surface of the as‐synthesized microstructured polypyrrole films. As a result, hierarchical structures of polypyrrole nanowires on polypyrrole microstructures are obtained. The surface wettabilities of the resulting nanowire‐based polypyrrole hierarchical structures are examined. It is expected that this two‐step method can be developed into a versatile route to produce nanowire‐based polypyrrole hierarchical structures with different morphologies and surface properties.
