Preparation of Functional Nan cylinder Arrays Using Templated Electrodeposition in Supercritical Fluids

A supercritical fluid exhibits larger diffusivility and lower viscosity compared to those of conventional liquids, since physicochemical properties of supercritical fluids are intermediate between those of gases and liquids. We envisioned that the use of scCHF_3 as an electrolytic medium for templated electrochemical deposition would enable the effective substrate transport into pores of template membrane and the nanoprecise filling with the materials. With this in mind, in this work, we have successfully developed a templated electrodeposition in supercritical fluids for preparation of functional nanocylinder arrays.
