Embodiment Construction
[0023] The inner and outer sides of the sinusoidal surface-shaped alumina template in this embodiment are sinusoidal surfaces, and the conical nanoholes are arranged radially and orderly along the vertical direction of the sinusoidal surface. Gradient, and can also be adjusted by changing the period, amplitude and anodizing time of the sinusoidal surface. The dotted arrow in the figure indicates the tangential direction of the template sinusoid.
[0024] For the alumina template in this example, the specific steps of its preparation method are:
[0025] (1) Cover the plane high-purity aluminum sheet on the surface of the sinusoidal surface mold, and obtain the sinusoidal surface aluminum sheet after forging and pressing, or remove the sinusoidal surface mold after vacuum evaporation of aluminum on the surface of the sinusoidal surface mold to obtain the sinusoidal surface aluminum sheet ;
[0026] (2) The sinusoidal surface-shaped aluminum sheet is polished in a mixture of e...

A sine curved alumina template for preparing nanomaterials and a preparation method thereof. It is characterized in that the inner and outer surfaces of the template are both sinusoidal surfaces, the conical nano-hole arrays are arranged radially and orderly along the vertical direction of the sinusoidal surface, and the pore size and pore size change rate of the conical nano-pores are tangentially gradient along the sine line, and can also pass Change the period, amplitude and anodization time adjustment of the sinusoidal surface. The preparation method is obtained by polishing, anodic oxidation and removing the barrier layer of a sine curved high-purity aluminum sheet. The sine curved alumina template in the present invention provides a convenient way for the synthesis of nanomaterials, and the preparation method thereof is simple and feasible.
Description
Technical field: [0001] The invention relates to a sinusoidal surface-shaped alumina template for preparing nanometer materials and a preparation method of the template. Background technique: [0002] With the continuous development of science and technology, many new disciplines continue to emerge. Nanomaterials is one example. The preparation of nanomaterials is the basis for the application of nanomaterials. At present, the methods used to prepare nanomaterials are: template method, vapor deposition method, photolithography method, liquid phase method, ion beam etching method and so on. The template method is one of the most basic methods. At present, there are about four mature templates: carbon nanotubes, ion beam etched carbon films, biological micromicelles and alumina templates. Alumina templates have become one of the most widely used templates due to their high pore density and adjustable nanopore aspect ratio (pore length / pore diameter). It is a nano-hole arr...
