One‐step electrodeposition of pyrrole on octadecyltrichlorosilane‐ (OTS) patterned silicon wafers results in positively patterned polypyrrole (PPy) structures, i.e., PPy deposits on the OTS‐covered area. In contrast, negative patterns are obtained on an indium tin oxide surface. The Figure shows electrically isolated positive PPy microwires on a silicon wafer.
