A device for preparing heterostructure anodized aluminum template

Abstract

The invention discloses a device for preparing a heterostructure anodic aluminum oxide template. The device comprises a phosphoric acid external oxidation system, an oxalic acid internal oxidation system, a power supply, a phosphoric acid circular flow system, an oxalic acid circular flow system, and a cooling water circulating tank; an external oxidation cathode ring is provided, is of a columnar structure with a closed bottom surface, and is arranged on the cooling water circulating tank; a raw material sealing caulking groove is of a ring structure and is positioned in the middle of the bottom of the external oxidation cathode ring; an internal oxidation cathode rod is fixed in the middle of the raw material sealing caulking groove; raw materials and the external oxidation cathode ring are connected with the power supply through a conductive support to form the phosphoric acid external oxidation system; and the internal oxidation cathode rod and the raw materials are connected with the power supply through the conductive support to form the oxalic acid internal oxidation system which is positioned in the phosphoric acid external oxidation system. The device disclosed by the invention can improve the production efficiency to obtain a large-area heterostructure template, and can achieve aims of controlling the temperature of a reaction environment and ensuring electrolyte concentration and composition uniformity through an electrolyte circular flow system.

Description

technical field [0001] The invention relates to a device for preparing a heterogeneous structure anodized aluminum template, in particular to a device for producing a heterogeneous structure anodized aluminum template by annular double-sided oxidation. Background technique [0002] Anodized aluminum template is a kind of micro-nano size hard template, which not only has good array space confinement function, but also has the characteristics of high temperature resistance, acid and alkali resistance, and high micro mechanical strength, so it is widely used in the preparation of nanomaterials , catalytic reaction, micro-scale separation technology, and micro-reaction container. In recent years, as the research hotspots of nanomaterial synthesis and micro-nano-scale structure device preparation continue to heat up, the demand for heterostructure anodized aluminum templates has also increased significantly. At present, whatman, the British company with the largest commercialized...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: at present, there is no standardized anodized aluminum template production and preparation device at home and abroad, so the sources of anodized aluminum templates are mostly self-prepared or self-produced and sold by some scientific research institutes or universities, and there is no difference in product quality. There is no guarantee and the process stability and operability are uneven when preparing templates. The most critical thing is that high-quality double-sided heterostructure anodized aluminum templates cannot be produced, and the output is extremely small.
