Fabrication of High‐Density, Large‐Area Conducting‐Polymer Nanostructures

The low‐cost, large‐scale fabrication of high‐density conducting‐polymer nanostructures is desirable for a variety of applications. We report the realization of high‐density conducting‐polymer nanostructures through a combination of nanoimprint lithography, a copolymer strategy, and a lift‐off process. Atomic force microscopy and optical measurements reveal that the quality of the prepared structures is rather good, and a resolution of 100 nm is achieved. Electrical measurements show that the conducting‐polymer nanowires are conductive and indicate great anisotropy in the parallel and perpendicular directions. Moreover, by further connecting them with larger electrodes, these nanowire arrays function as nanosensors.
