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...

[0024] The principle of the device described in this example is as follows: the biggest difficulty in preparing heterogeneous structure templates by double-sided oxidation is that because the common raw material aluminum foil is used as the anode, the voltage applied to the inner and outer oxidation surfaces is the same value, while different electrolytes need to be matched with different suitable materials. Voltage distribution is u...
