Problems solved by technology

It must be pointed out that it is difficult to deposit an aluminum layer of more than 600 nanometers on the substrate by thermal evaporation or magnetron sputtering with the existing technology, so only one anodic oxidation experiment can be carried out, and the order degree of porous alumina is obvious. reduce

Abstract

The invention discloses a method for preparing an orderly one-dimensional nanometer array on a conductive substrate. The method includes the following steps that S1, a through-hole anode aluminum oxide template is prepared; S2, the conductive substrate where a gold film is formed through magnetron sputtering is put in a sulfydryl silane solution to be soaked and is then put in hydrochloric acid to be soaked; S3, the through-hole anode aluminum oxide template is attached to the gold film of the conductive substrate processed in the step S2, and is subjected to high-temperature dehydration processing; S4, the one-dimensional nanometer array is synthesized on the through-hole anode aluminum oxide template attached to the gold film of the conductive substrate through electrochemical deposition; and S5, after the through-hole anode aluminum oxide template is removed, moisture on the surface of the one-dimensional nanometer array is washed away, and the orderly one-dimensional nanometer array standing on the conductive substrate is obtained. According to the method, by attaching the through-hole anode aluminum oxide template to the gold film of the processed conductive substrate, the highly-orderly one-dimensional nanometer array is obtained through electrochemical deposition.

Description

technical field [0001] The invention relates to the technical field of nanomaterial preparation, in particular to a method for preparing an ordered one-dimensional nanoarray on a conductive substrate. Background technique [0002] Highly ordered one-dimensional nanostructures such as nanowires, nanorods, and nanotubes have important applications in optical components, biosensors, magnetic memory storage, solar cells, and biomedicine, while porous alumina templates have a wide range of pore sizes. The characteristics of adjustable, precisely adjustable aspect ratio, regular and orderly pores, and high temperature resistance have been widely used in the synthesis of one-dimensional nanostructures. [0003] Electrochemical deposition of one-dimensional nanostructures using porous alumina as a template is a widely used method, which has attracted people's attention because of its simple and convenient operation method, and the length of nanostructures can be simply controlled by...
