Abstract

The invention discloses a preparation method of a novel ZnO-nanosheet-structure coating, belonging to the field of preparation of nano-structure coating materials. The method comprises the following steps: preparing a ZnO seed layer sol by a sol-gel process; preparing a ZnO seed layer film by a dip-coating process, and carrying out heat treatment in a muffle furnace; carrying out hydrothermal growth on the prepared ZnO seed layer film in the prepared ZnO growth solution; and finally, after the hydrothermal reaction finishes, continuing the corrosion reaction in the original growth solution for some time, and taking out the sample, thereby obtaining the novel ZnO-nanosheet-structure coating material. The observation and test by a scanning electronic microscope can be performed on the novel ZnO-nanosheet-structure coating to obtain the shape rules of the ZnO-nanosheet-structure coating. The method disclosed by the invention is a nontoxic green chemical technique, and does not generate secondary hazards; the method is low in cost and easy to implement; and the method has the characteristics of simple preparation technique and favorable feasibility.

Description

technical field [0001] The invention belongs to the field of preparation of nanostructure coating materials, in particular to a preparation method of a novel ZnO nanosheet structure coating. Background technique [0002] In our country, the research of nanomaterials and nanotechnology is gradually being highly valued by all parties. In order to vigorously develop the research level of nanotechnology in our country, the country has passed the implementation of "863" and "973" plans. At present, most of my country's nano-products are concentrated in nano-powders, which are used in textiles, plastics, ceramics, coatings and other fields, but these are still in the initial stage of research. [0003] Generally speaking, there are two different application methods for nano-coating materials, which are: one is to form composite nano-coatings by dispersing nanoparticles in traditional organic coatings, and then spray them on the base material to form a coating. The role of nanopar...
