preparation example Construction

[0017] A method for preparing a nano-ordered zinc oxide thin film material, comprising the following steps: (a) configuring an alkali solution, and adding a surfactant and additives to the alkali solution to prepare an alkali corrosion solution; (b) activating the zinc matrix; Put the polished zinc substrate into ethanol and ultrasonically wash it for 1-10 minutes, and then soak it in acetone for 1-10 minutes; (c) Soak the activated zinc substrate in alkaline corrosion solution for 10-60 seconds ; (d) Take out the zinc matrix and put it into a temperature control device, keep the temperature at 10-80oC, and place it for 0.5-5 hours; (e) Take out the zinc matrix, wash and dry it, and get a nanometer with zinc as the matrix. Ordered zinc oxide thin film material; the alkali solution is NaOH or KOH solution with a concentration between 2mol / L; One of them or two or three mixed in any proportion, the amount of surfactant added is 0.01-2g per 1L of alkali solution; the additive is ...

Embodiment 1

[0022] Prepare 10 ml of 2 mol / L KOH solution with deionized water, add 0.02 g of sodium dodecylsulfonate, and then add 2 ml of ammonia water to prepare a lye that corrodes the zinc matrix. Cut a zinc sheet about 2 cm long and 1 cm wide as the zinc matrix, polish it with sandpaper, then ultrasonically clean it in ethanol solution for 1 minute, and then soak it in acetone for about 1 minute. Soak the activated zinc matrix in lye for 10 seconds to wet it, take it out with tweezers, and a layer of liquid film will naturally form on the surface of the zinc matrix. Carefully put the wetted zinc matrix into the glass tube, and lightly plug the glass tube's mouth with a stopper, but do not seal it. After reacting at 10°C for 5 hours, the sample was taken out, washed with deionization, rinsed with ethanol, and then dried to obtain zinc oxide nanomaterials. its description see figure 1 , the product is a highly ordered nanorod array with a diameter of about 30 nanometers, a length of ...

Embodiment 2

[0024] In addition to adding 0.0001g of sodium dodecylsulfonate to obtain a lye for corrosion of zinc matrix, other steps are the same as in Example 1. The resulting product looks like figure 2 , the product is a larger hexagonal column (rod) array.
