Evolution of morphology, structure, and magnetic parameters of Ni nanotubes with growth in pores of a PET template

Abstract

Metallic nanostructures such as nanorods, nanowires, and nanotubes are of great interest from fundamental and applied perspectives. In this work, we studied one-dimensional nickel nanostructures with variable lengths approximately 2–12 μm and wall thickness approximately 70–120 nm grown electrochemically in the pores of PET templates. The synthesis technique and the results of sample characterization including morphological features, texture, crystal structure, and magnetic properties are presented.
