Abstract

The present invention discloses single side anodization aluminum shuttering preparation device. It includes a quadratic teflon shell with slot on four internal surfaces for inserting lead plate, lead plate having electrolyte flow seam on upper surface and electrolyte container on shell bottom, four side surfaces having rectangular step slot with rectangle window, interval formed between lead plate and rectangle window inner side surface, interval between lead plate and rectangle window inner side surface and lead plate upper electrolyte flow seam to form electrolyte convective circulation loop. Said invention Adopts multiwindow design, making one surface of aluminum foil contacting air outside the container, another surface contacting electrolyte solution in container, such structure effectively preventing aluminum foil both sides simultaneously oxidization, thereby reaching preparation aluminium oxide templet.

Description

The preparation facilities of single surface anode aluminum oxide templete

Technical field

The present invention relates to be used to prepare the device that contains the nano-pore structure alumina formwork, especially relate to a kind of preparation facilities of single surface anode aluminum oxide templete.

Background technology

Alumina formwork (AAO template) is widely used in nano material preparation, can prepare nano wire, nanotube and nanometer rod etc. by the AAO template.At present, the preparation facilities of single face AAO template adopts the one side at aluminium foil to be coated with the insulation grease and guarantees to have only the oxidized pore-forming of one side, because greasy existence is polluted electrolytic solution and aluminium foil, and electrode distance exists uncertain, these factors all cause the poor repeatability of AAO template preparation process condition, and different operations can not finish on same device, complicated operation, and preparation efficiency is lower.

Summary of the invention

In order to overcome the defective that existing AAO template preparation facilities prepares single sided pattern plate, the purpose of this invention is to provide a kind of preparation facilities of single surface anode aluminum oxide templete.

The technical solution adopted for the present invention to solve the technical problems is: be respectively equipped with the draw-in groove that can insert stereotype on four internal surfaces of foursquare tetrafluoroethylene housing, have the electrolyte stream seam above the stereotype, foursquare tetrafluoroethylene housing bottom is an electrolyte container, on four sides of foursquare tetrafluoroethylene housing, have rectangular step groove, step groove intermediate formation rectangle window, leave the gap between stereotype and the rectangle window medial surface, gap between stereotype and the rectangle window medial surface and the seam of the electrolyte stream above the stereotype form electrolytic solution convection circulation loop.

The beneficial effect that the present invention has is: adopt the design of multiwindow formula, aluminium foil can be close to each window, make the outer air of contacting container of aluminium foil, electrolyte solution in the another side contacting container, this has just prevented effectively that the aluminium foil two sides is simultaneously oxidized, thereby reaches preparation single face AAO template.All process steps can all be finished in this device, and electrode distance is strict to be determined, the processing condition good reproducibility, and oxidizing reaction can be carried out the preparation efficiency height simultaneously at four windows.

Embodiment

The present invention is further described below in conjunction with drawings and Examples.

As Fig. 1～shown in Figure 12, on 1 four internal surfaces of foursquare tetrafluoroethylene housing, be respectively equipped with the draw-in groove 9 that can insert stereotype 2, have electrolyte stream seam 6 above the stereotype 2, foursquare tetrafluoroethylene housing 1 bottom is an electrolyte container 10, on 1 four sides of foursquare tetrafluoroethylene housing, have rectangular step groove 7, step groove 7 intermediate formation rectangle windows 8, leave the gap between stereotype 2 and rectangle window 8 medial surfaces, gap between stereotype 2 and rectangle window 8 medial surfaces and the seam of the electrolyte stream above the stereotype 26 form electrolytic solution convection circulation loop.

The specific embodiment of the invention is as follows:

As shown in Figure 9, earlier four blocks of sheet leads 2 are inserted in tetrafluoroethylene housing 1 draw-in groove 9 separately and form AAO template preparation facilities shown in Figure 1, when requiring assembling electrolyte stream seam 6 is positioned at the top of housing, stick teflin ring 5 successively at step groove 7 then, aluminium foil 4 and polycarbonate thin plate 3 that one end is distorted, and with clamp polycarbonate thin plate 3, wherein teflin ring 5 is in order to prevent that electrolytic solution from spilling from electrolyte container 10, the polycarbonate thin plate 3 that clamps is in order to make teflin ring 5 and aluminium foil 4 closely be affixed on step groove 7, make good seal, also make aluminium foil 4 can bear the pressure of electrolytic solution in the electrolyte container 10.Four windows are all used this method sealing, final whole embodiment forms the container of sealing fully, then electrolytic solution is poured in the container, electrolytic solution surpasses electrolyte stream seam 6, at last power cathode is added on the sheet lead 2, and power anode is added on the aluminium foil 4, magneton 12 is put in bottom at electrolytic solution 10 containers, whole device is placed on the magnetic stirring apparatus, helps electrolytic solution like this and form the convection circulation loop under the stirring of magneton 12, makes aluminium foil 4 temperature-stable in oxidising process.Rotate magneton 12 at last and stir electrolytic solution.Purpose is the anodic oxidation aluminium formwork that obtains having nano-pore structure for oxidation.Electrolyte solution in the air that contacting container of aluminium foil is outer, another side contacting container, this has just prevented effectively that the aluminium foil two sides is simultaneously oxidized, thereby reaches the purpose of preparation single face AAO template.By suitable whipping appts, and design has the circulation of elecrolyte of promotion mobile stream seam, can effectively disperse the heat that electrode produces in the preparation process, guaranteed the systematicness of prepared AAO pattern hole in preparation process.

Above-mentioned embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
