A fabrication setup was specially designed so that one stream of sol of polyvinyl pyrrolidone (PVP), electrospun to form a bundle of fibers, acted as an axis between two rotating needles, and a second stream of PVP sol containing copper nitrate was electrospun around the fiber bundle axis to form a coil. This was turned into a coiled ribbon upon treatment in moisture. After calcination and reduction, a helical microcoil of nanocopper ribbon was produced, with controlled diameter and pitch. The width and thickness of the ribbon could be varied by manipulating the diameter of the coiled fiber and its treatment time in moisture.
