Double pass AAO template, preparation method and application of double pass AAO template

Abstract

The invention belongs to the technical field of electrochemistry, and relates to a template-electrochemistry deposition technology, in particular to a double pass AAO template, a preparation method and application of the double pass AAO template. The A face of an aluminum sheet coated with a gold coating is attached to an aluminum foil to be packaged plastically, so that the aluminum foil provides the gold-steamed double pass AAO template with good dynamic support and electrical contact, and the double pass AAP template can serves as a working electrode directly when being applied to electro-deposition nanowire technology. By using the method, the prepared double pass AAO template can guarantee the uniformity and stability when being used as electro-deposition nanowire, and the filling rate is high, can serve as the working electrode directly to be applied to the electro-deposition nanowire technology, and has no application defects which exist in the prior art.

Description

technical field [0001] The invention belongs to the field of electrochemical technology, relates to a template-electrochemical deposition technology, in particular to a double-pass AAO template and its preparation method and application. Background technique [0002] AAO template (Anodic Aluminum Oxide Template, anodic aluminum oxide template) is a transparent template with nano-apertures. The pore size is uniform and the distribution is highly ordered. It can synthesize a variety of structures (tubes, rods, wires, etc.) and has good dispersion. of nanomaterials. The one-dimensional nanostructure array prepared by the electrochemical deposition method is smooth and uniform in diameter, without complicated post-processing, and the purpose of composition and structure regulation of one-dimensional nanomaterials can be achieved by changing the deposition voltage and deposition time. The template-electrodeposition method makes it easier and more convenient for people to design ...

Problems solved by technology

However, the method used in the subsequent application of the electrodeposition process is quite different. The current common practice is to fix the double-pass AAO template on the copper plate with wires through silicon rubber, and conduct electricity through the contact between the copper plate and the AAO template. The common AAO template is fragile. This method is very easy to cause the template to break when the silicone rubber is processed in the later stage, and some of the silicone rubber sticks to the AAO template, which will seriously affect the later testing process; The fixture is designed in plastic, but there is a problem with the sealing of the fixture, which often causes the solution to overflow and most of the fixtures use the template and the copper plate to press together. A little carelessness will cause the template to be broken and the conductivity will be uneven, resulting in the filling rate of the template. not tall
