Problems solved by technology

During the preparation process of the current AAO porous nano-template, due to the absence of a suitable standard support bracket, the self-made mechanism of the researchers is complex and inapplicable. The substrate used to prepare the AAO porous nano-template is prone to fracture due to its thin thickness. Moreover, the sealing performance is poor, and the acid solution of the electrolyte often penetrates, causing corrosion to the wires connected to the substrate, making the device unable to be used effectively for a long time, which is not conducive to the application of large-scale industrialization

Abstract

The invention relates to the technical field of anodic aluminum oxide porous membranes, in particular to an electrochemical deposition support for preparing a nano material. The support comprises a substrate, a front cover plate, a support base and a conductive assembly, the substrate is fixed through the front cover plate and the support base, the conductive assembly is arranged on the support base, the substrate is connected with the conductive assembly, and a through hole A is further formed in the front cover plate in a penetrating mode. According to the support, the structure is stable, the fixing effect of the substrate is good, the sealing performance is good, and the conductive assembly can be prevented from being corroded by an electrolyte; the whole body is of an assembly type structure, no glue or bonding structure is arranged, disassembling, assembling and parts replacement are easy, and the long-term effective use of the device is facilitated.

Description

technical field [0001] The invention relates to the technical field of anodized aluminum oxide porous membranes, in particular to an electrochemical deposition support for preparing nanometer materials. Background technique [0002] AAO porous nano template is a kind of anodized aluminum template, which has the advantages of uniform distribution of pore height, uniform pore size, controllable pore shape and large surface area, and has a good market application prospect. Using double-pass AAO as a template, metal nanowires with high aspect ratio and high density can be conveniently prepared by electrochemical deposition. Importantly, in order to ensure that the nanowires grow only in the nanopores inside the template, the template must be effectively sealed, leaving only the parts that need to be reacted exposed in the electrolyte. In addition, in order to ensure the uniformity of the nanowire growth process, it is necessary to fully consider the influence of the structure o...
