Problems solved by technology

The film material prepared by the above-mentioned material surface treatment technology or deposition technology is always attached to the surface of the substrate (or part), in fact it is a surface film, which is always combined with the substrate, and the thickness of the substrate material is much larger than The thickness of the film material, in this case the film material cannot be used alone
However, in many cases, pure metal compound films have properties different from those attached to the substrate, and are widely used in industrial production, but the existing technology still cannot prepare pure metal compounds that are not attached to the substrate material Compound film material

Embodiment 1

[0019] Use a pure aluminum sheet with a thickness of 30 μm as an anodized anode and put it in a sulfuric acid electrolytic solution with a concentration of 1mol / L. The temperature of the sulfuric acid electrolytic solution is 3°C, and the anode current density is 4A / dm 2 , the voltage of the electrolytic cell is 100V; during this process, the aluminum is oxidized and converted into aluminum oxide, and through pores are formed in the thickness direction, and the size of the pores can be controlled by adjusting the process parameters. The invention converts pure aluminum flakes into aluminum oxide ceramic membrane materials with tiny through-pores through anodic oxidation, which can be used for fine filtration of gas and liquid.

Embodiment 2

[0021] Put the bulk sulfur in a glass beaker, heat it in a heating furnace to 130°C, and keep it warm to make the sulfur melt into a liquid, then unfold a 10μm thick zinc foil and soak it in the sulfur liquid, and vacuumize the heating furnace , continue to keep warm, so that the zinc foil and sulfur fully react to form zinc sulfide, after the zinc foil is converted into zinc sulfide foil, the zinc sulfide foil material is taken out of the sulfur solution, thereby preparing a zinc sulfide film material with photosensitive function.

Embodiment 3

[0023] Spread the tin foil with a thickness of 5 μm and place it in a heating furnace filled with oxygen, heat it to 200°C, and keep it warm to oxidize the tin into tin oxide. After the tin foil is converted into tin oxide foil, take the tin oxide foil material out of the heating furnace, The tin oxide film material with gas sensing function is prepared.

Abstract

The present invention provides a preparation method of metal compound membrane material. Said method includes the following steps: making metallic diaphragm whose thickness is less than 100 micrometers participate in chemical reaction and making whole metallic diaphragm be converted into the thin metal compound so as to obtain the invented metal compound membrane material. Said invention is simple, can be used effectively for preparing nano-grade metal compound membrane material.

Description

technical field [0001] The invention relates to the technical field of membrane materials, in particular to a preparation method of a metal compound membrane material. Background technique [0002] The current preparation method of inorganic compound film material is to use material surface treatment technology or deposition technology to form a film with a thickness of nanometer to micron scale on the surface of the substrate (or part). Surface treatment methods mainly include surface diffusion infiltration method, chemical conversion method, electrochemical conversion method, etc. For example, the Chinese invention patent with application number 01107430.2 describes a method for rapid anodic hard oxidation of aluminum pans, which is characterized in that aluminum pans are After decontamination in alkaline solution at normal temperature, add surfactant to activate at 40°C-50°C, then perform hard anodic oxidation treatment, and finally seal the surf...
