Abstract

The invention discloses a method for preparing an anodic alumina template by using a plastic packaging process and application thereof. The core point of the method is that the plastic packaging process is utilized for insulation blocking on one surface needing no reaction or treatment of an aluminum sheet, and the method comprises the following steps that: during electrochemical polishing of the aluminum sheet, one surface of the aluminum sheet is sealed by using the plastic packaging process, and the other surface of the aluminum sheet is exposed for polishing; during anodic oxidation of the aluminum sheet, only the surface exposed for polishing is subjected to anodic oxidation due to insulation blocking resulting from plastic packaging; during removal of an aluminum base, by utilizing sealing protection of plastic packaging to the alumina template, a surface of the aluminum base is exposed in a solution and removed so as to obtain the anodic alumina template. The anodic alumina template prepared by the method is colorless and transparent, has a high degree of order and is easy to preserve. According to the invention, high quality alumina templates can be prepared by using plastic package glue cover without any special equipment, and preparation of an alumina template with a large area is made to be simple and easy, thereby greatly improving a success rate of preparing templates, reducing preparation cost for the templates and having remarkable economic benefits.

Description

technical field [0001] The invention relates to the electrochemical preparation of templates, in particular to a method and application for preparing anodized aluminum templates by using a plastic sealing process. Background technique [0002] A template refers to a film containing high-density columnar holes with a thickness of tens to hundreds of microns. Porous alumina template is the most widely used template so far. The micropores in the membrane are highly ordered and have good thermal and chemical stability. It is an ideal inorganic template for preparing nanoelectronic materials with highly uniform and ordered shapes. Porous alumina templates can be prepared by anodic oxidation of high-purity aluminum in acidic solution. This type of film has many cylindrical pores arranged in a hexagonal array with uniform pore diameters, and the pores are parallel to each other and perpendicular to the membrane surface. The pore diameter of the aluminum oxide film is up to 200 na...
