Abstract

The invention discloses a method for preparing an independent metal nanoribbon, relating to the technical field of nanometer materials. The method comprises the following steps: crystallizing on a monocrystalline silicon wafer or a single crystal alumina wafer or other crystalline matrixes to generate a strip-shaped template by utilizing oxalic acid and other template solutions; plating metals onto the strip-shaped template by adopting a vacuum coating process; dissolving and removing the strip-shaped template by using a solvent, thereby obtaining the independent metal nanoribbon. The method disclosed by the invention is simple in process and is suitable for preparing multiple metal nanoribbons; and moreover, the prepared metal nanoribbon is controllable in thickness, the needed equipment is low in price, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a method for preparing an independent metal nanobelt. The prepared metal nanobelt can be used to prepare metal electrodes for micro / nano devices, or as a sample for studying the properties of nanomaterials. Background technique [0002] One-dimensional metal nanostructures, such as nanowires, nanorods, nanotubes or nanoribbons, are key components for fabricating nanodevices. In particular, nanoribbons can be used as samples to study size-limited transport phenomena; they can also be used to prepare functional devices along the direction of nanoribbons, including electrical, chemical, physical and thermal functional devices. [0003] Nanomaterials have large surface areas and should behave very differently from bulk materials. Many researchers study the properties of nanoribbons theoretically, but the data of experimental research results are still very scattered...
