Synthesis of Cobalt/Polymer Multilayer Nanotubes

Abstract

Cobalt/polymer multilayer nanotubes (see Figure) are formed by wetting of alumina and silicon membranes by polystyrene containing a metallo–organic precursor, followed by a thermal decomposition process. This article describes the fabrication and magnetic properties of high quality, thin‐walled ferromagnetic nanotubes. They might be very attractive for a broad range of potential applications ranging from biotechnology to magnetic storage devices.
