preparation example Construction

[0009] In conjunction with the accompanying drawings, the preparation method of the zinc oxide nano film of the present invention comprises the following steps: first, in concentrated hydrochloric acid, add butyl zincate, stir, the solution presents a transparent and clear shape, prepare a precursor solution, and spread it on the culture In the container; secondly, add the surfactant into the water, heat and stir to obtain the template solution; then, after the template solution is cooled, pour it evenly into the culture container, transfer it to the artificial intelligence climate box, and let it stand for self-assembly to obtain ZnO nanofilms. Among them, the surfactant is sodium dodecylsulfonate SDS1, sodium dodecylsulfate SDS2, sodium dodecylbenzenesulfonate DBS-Na, 1-sodium naphthalenesulfonate 1-SNS or 2-naphthalenesulfonic acid Sodium 2-SNS. Protein gelatin can be added to the surfactant as a film-forming aid. The mass ratio of surfactant to gelatin is 1:1-2:1. The m...

Embodiment 1

[0012] Step 1, dissolving 0.84g of butyl zincate in 0.64g of 37% concentrated hydrochloric acid HCl, and magnetic stirring for 10min to obtain a clear precursor solution;

[0013] Step 2, spreading the above solution in a plastic petri dish;

[0014] Step 3, dissolve 0.15 g of the surfactant sodium dodecylsulfonate (SDS) in 18.4 ml of deionized H 2 O, heated to 40°C with magnetic stirring for 15 minutes to obtain a uniformly mixed templating agent, and cooled at room temperature;

[0015] Step 4, when the temperature of the above-mentioned cooling solution is slightly higher than normal temperature (about 25°C), pour it evenly into the petri dish;

[0016] Step 5, transfer the petri dish to a thermostatic chamber (keep the film growth temperature at 21° C.), and let it stand still. After about 12 hours, the self-assembly process is completed to obtain a zinc oxide nano film.

[0017] The present invention uses the obtained zinc oxide nano film as the starting material, heats...

Abstract

The invention discloses a method for preparing a zinc oxide nano membrane, which comprises the following steps: firstly, adding butyl caprylate in concentrated hydrochloric acid and stirring thebutyl caprylate and the concentrated hydrochloric acid so that the solution is transparent and clear, the precursor solution is prepared and is paved inside a culture container; secondly, adding a surface active agent into water to be heated and stirred so as to obtain a template agent solution; thirdly, evenly pouring the cooled template agent solution to the culture container, and transferring the culture container to an artificial intelligent climatic chamber to keep stand for self assembling to obtain the zinc oxide nano membrane. A serial detection devices show that the zinc oxide nano membrane obtained by self-assembly has the ordered nano structure observed under nanoscale; the prepared zinc oxide nano membrane suspends on the surface of the solution, and the density of the prepared zinc oxide nano membrane is remarkably lower than that of the zinc oxide nano membrane prepared by a conventional method. The preparation technique has a certain popularization value and can be applied to preparing other inorganic oxide nano membranes.

Description

technical field [0001] The invention belongs to the preparation technology of inorganic materials, in particular to a preparation method of zinc oxide nano film. Background technique [0002] The self-assembly method is a phenomenon in which several molecules of the same type or different types of molecules are spontaneously combined and stacked mainly through supramolecular forces. Most of the formed assemblies are ordered structures, which can effectively design highly ordered structures with specific physical and chemical properties. Mesoscopic structure of the material, and often with a specific geometric configuration. With the development of nanotechnology, this method has been introduced into the chemical preparation research of inorganic nanocrystals, and has been endowed with new connotations. Now it has become one of the most studied and extensive chemical methods for preparing nanomaterials. . [0003] The traditional preparation of zinc oxide nano-film mainly i...
