Abstract

It is the producing method of multi-hole Al2O3 form board and the related device. It is about a kind of hard form board. The invention has simplified prior period's treatment, easy operation during the experiment, easily-got device and solvent, short time of producing and small amount of drug. The device has electrolyzing cell, capping, the positive pole and its leading-out wire, the negative pole and its leading-out wire and the magnetic stirring apparatus. The cell wall's structure is hollow with double layer, and on the wall set the water-entry hole and water-exiting hole, which are linked with the hollow internal cavity. The capping is set atop the electrolyzing cell, and meanwhile the positive pole and the negative one are set in the electrolyte. The positive pole is Al flake, and the negative one is Pt flake. Firstly, the Al foil should be burnished, the burnishing casket heated by water. After burnished, the Al foil is put into the electrolyzing cell, which is set in the temperature below the room-temperature. After oxidized, the Al foil is immersed in the saturated HgCl2 solution. Then wash off the Al2O3 thin coat which has leaved the Al base. At last, immerse it in the H3PO4 until the interlock is formed.

Description

technical field

[0001] The invention relates to a hard template, in particular to a porous alumina template which can be mainly used to prepare regularly arranged nanometer materials. Background technique

[0002] The porous alumina template is the most commonly used hard template, and it is a hard template that is anodized on the surface of high-purity aluminum foil to form a porous membrane. Its structural feature is that it has hexagonal cylindrical parallel holes of uniform size at the nanoscale, and nanomaterials with very regular arrangements can be made using this as a template. Alumina is an inorganic material. Compared with other templates, it has many advantages, such as low preparation cost, simple preparation process conditions, stable existence in high temperature and organic solvents, and easy adjustment of pore size and depth parameters. The preparation of traditional anodized aluminum templates requires pre-oxidation pretreatments such as high-temperature an...
