Description

technical field [0001] The invention relates to a special program-controlled power supply system for nano-processing. The system is suitable for the processing of materials such as anodized aluminum nano-tube arrays and the preparation of other metal and non-metal nano-tubes using it as a template, and can also be used for other nano-research oxidation nano-materials Preparation and biochemical analysis belong to the field of electronic technology. Background technique [0002] At present, anodized aluminum oxide membranes are widely used in the fields of preparation of nanomaterials, separation science, and biochemical analysis, so the preparation of anodized aluminum oxide membranes has become a bottleneck in its application. The preparation of the nano-hole array aluminum oxide film is obtained by anodizing the aluminum electrode, and the subsequent aluminum oxide film peeling adopts the potential pulse method invented by us. Both processes need to provide high potential,...
