Embodiment 1

[0022] 1. Clean the substrate. The substrate (metal, ceramic or polymer material) is completely submerged in ethanol, cleaned for a period of time under ultrasonic conditions, and then washed several times with deionized water, and then put in an oven to dry at a certain temperature for several hours.

[0023] 2. Growth solution preparation. Use a sealable glass or plastic container to mix magnesium salts (one or more of magnesium nitrate, magnesium chloride, magnesium sulfate, magnesium acetate) and doping component metal salts (lithium salts, copper salts, titanium salts, cobalt salts, One or more of manganese salts) are dissolved in water, and then a certain proportion of forming reactants (urea, one or two of hexamethylenetetramine) is added. After fully dissolving, the substrate is completely immersed in the growth solution.

[0024] 3. Growth response. Heat the closed container in 2 to 60-120 ºC in an oven or other heating means and keep at this temperature for 2-12 h...

Abstract

The invention discloses a preparation method of a sheet type magnesium oxide or magnesium oxide-doped array. The method comprises following steps of (1), cleaning a substrate; (2), preparing a growthsolution; (3), growth reaction; (4), cleaning and drying; and (5), high-temperature post-treatment. Aiming at the problems existing in the existing nano magnesium oxide particles application, according to the method, a hydrothermal growth technology is directly adopted, the magnesium oxide nano sheet type array is grown in situ on the commercial substrate (metal, ceramic and polymer fibers) surface so as to produce nano-array-based magnesium oxide antibacterial material. A novel magnesium oxide nano array-based film of the material has excellent mechanical stability, a unique array space structure, a large specific surface area and rich hole structures.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a sheet-like magnesium oxide or doped magnesium oxide array and a preparation method thereof. Background technique [0002] Magnesium oxide (MgO) is a very important industrial raw material, which is widely used in the fields of metallurgy, ceramics, catalysis, coatings, medicine, adsorption materials, refractory materials and optical materials. With the development of science and technology, magnesium oxide with different structures and functions has been continuously developed, including high-purity magnesium oxide for energy-saving lamps and plasma displays, porous magnesium oxide for catalysis and biological gene repair, and Magnesium oxide single crystal of low temperature optical devices, high temperature superconducting devices, etc. In recent years, nano-magnesium oxide (nano-MgO) has become a new type of functional inorganic material due to its optical, electrical, ma...
