Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the examples and comparative examples, but the present invention is not limited to the scope of the examples.

[0014] Chemically pure Zn(NO 3 ) 2 6H 2 O and hexamethylenetetramine ((CH 3 ) 6 N 4 ) was dissolved in deionized water and stirred evenly to obtain a stable transparent solution;

[0015] Put the cleaned conductive slide into the solution, and then heat the solution to 75°C in a water bath;

[0016] Add chemical modifier mercaptosuccinic acid after heating for 1h;

[0017] After continuing to keep warm for a period of time, the conductive slide is taken out, cleaned with deionized water, and finally dried with warm air to obtain a chemically modified ZnO nanorod array film on the surface of the base material.

[0018] Compared with the prior art, the present invention mainly differs in that a chemical modifier is added on the basis of the prior sol-gel technology, so that the su...

Abstract

The invention discloses a method for preparing ZnO nano-rod array film with eutopic chemical modification by adopting a sol-gel method. The method comprises the following steps; (1) Zn (NO3)26H2O and hexamethylene tetramine are dissolved in deionized water and are then evenly stirred; (2) the cleaned substrate material is placed into the solution and the solution is heated; (3) after the solution is heated for a certain time, chemical modifier is then added into the solution; (4) the temperature is continuously kept and the substrate material is then taken out from the solution and is cleaned with the deionized water. The substrate material is finally dried by warm wind and the ZnO nano-rod array film with eutopic chemical modification is obtained. In a certain concentration, the invention not only can effectively control the generation of the hexagonal phase ZnO nano-rod for forming the array film, but also realize a chemical modification on the surface of the ZnO nano-rod, thus shortening the technological process and realizing a cheap large scale production; therefore, the ZnO nano-rod has more practical meanings. The ZnO nano-rod array film with bit chemical modification has a wide application value in the fields of electronic information, photoelectric signal, biology information detection, disease diagnosis, etc.

Description

technical field [0001] The invention relates to a method for preparing a ZnO nanorod array film by chemical modification, in particular to a method for preparing a ZnO nanorod surface chemically modified array film by using a sol-gel method. Background technique [0002] Zinc oxide (ZnO) is zinc oxide as an important semiconductor and piezoelectric nanomaterials. The bandgap width and exciton binding energy are 3.37eV and 60meV, respectively. Efficient exciton luminescence can be obtained at room temperature. It has broad application prospects in display, electroluminescence, low-voltage field emission display, laser, optoelectronic devices, sensors and energy converters. [2-3] . Compared with other semiconductor nanomaterials, nano-zinc oxide has exceptionally rich special morphology, such as: flower shape, ring shape, ribbon shape, tetrapod shape, sheet, tower shape, cage shape and propeller shape, etc. These rich and special morphologies may enable them to have some new...
