specific Embodiment approach 1

[0024] Specific embodiment 1: This embodiment is a method for preparing silver nanowire arrays by using capillary wetting, specifically according to the following steps:

[0025] 1. Mixed powder: Put Ag powder and CuO powder together into a ball mill jar, add absolute ethanol to completely submerge Ag powder and CuO powder, wet mix ball mill in planetary ball mill for 6h~12h, then take it out, and put it at 90℃~95 Dry in a water bath at ℃ to obtain Ag-CuO mixed powder, and then use a tablet mold to make Ag-CuO mixed powder into Ag-CuO sheets under the pressure of a hydraulic press; the mole of CuO in the Ag-CuO mixed powder The score is 1% to 8%;

[0026] 2. Heating: polish the base material, and then ultrasonically clean it with absolute ethanol for 5-10 min; rinse the anodized aluminum template in absolute ethanol, and dry it naturally; wash the base material and the Ag- The CuO sheet and the dried anodized aluminum template were stacked together from bottom to top, placed ...

specific Embodiment approach 2

[0028] Embodiment 2: This embodiment is different from Embodiment 1 in that the mole fraction of CuO in the Ag-CuO mixed powder described in step 1 is 1%. Others are the same as the first embodiment.

specific Embodiment approach 3

[0029] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the base material described in step two is a high-temperature stable ceramic material, specifically Al 2 o 3 or BSCF, BCFN or BCFZ. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a method for preparing silver nanowire arrays by using capillary wetting effect, and relates to a method for preparing the silver nanowire arrays. The method aims to solve the technical problems that an existing silver nanowire array is complex in preparation process and poor in binding property with a target matrix. The method comprises the following steps of 1, mixing Ag powder with CuO powder; 2, heating the mixed powder; and 3, carrying out hydrothermal reaction. The method for preparing the silver nanowire arrays on an inert metal surface or a ceramic surface by using the capillary wetting effect is simple and effective in operation; and meanwhile, a method for removing a phase-changed AAO template through corrosion is provided, and the application prospect is good.

Description

technical field [0001] The invention relates to a method for preparing a silver nanowire array. Background technique [0002] Silver nanowire arrays have unique photoelectric properties, high detection sensitivity and good catalytic performance, so they have broad application prospects. At present, the preparation of silver nanowire arrays mainly adopts the method of electrochemical deposition. First, a layer of Au is deposited or sputtered on the surface of the anodized aluminum oxide template (AAO) to make it conductive, and then the AAO is used as an electrode. + Electrodeposition was carried out in the solution of AAO, and silver nanowires were prepared in the nanopores of AAO, and then the AAO template was removed by acid or alkali solution to obtain silver nanowire arrays. However, the operation of this electrodeposition method is relatively complicated, and the obtained silver nanowire array needs to be subsequently transferred to the target substrate, and lacks a go...
