Metallic nanospring and method for manufacturing of the same

摘要

A method for manufacturing a metallic nanospring includes preparing a nanotemplate having a nanopore and including a working electrode disposed on its one surface, preparing a first metal precursor mixture including ascorbic acid (C₆H₈O₆), vanadium (IV) oxide sulfate (VOSO₄.xH₂O), and a metal precursor solution including a metal desired to be deposited, preparing a second metal precursor mixture by mixing the first metal precursor mixture with nitric acid (HNO₃), depositing a metallic nanospring into the nanopore using electrodeposition by dipping the nanotemplate into the second metal precursor mixture and applying current between a counter electrode inserted into the second metal precursor mixture and the working electrode, and selectively removing the working electrode on the nanotemplate with the deposited metallic nanospring and the nanotemplate.
