Embodiment 1

[0029] At room temperature, add 1.4g PVDF powder, 10mL DMF solution, 2ml of DMF solution of 0.1mmol / mL copper nitrate trihydrate, 8ml of DMF solution of 0.025mmol / mL trimesic acid in a beaker, and put the mixed solution at room temperature Stir evenly, then apply it on the glass substrate and transfer it to an oven, keep it at 120°C for 30 minutes, after it is naturally cooled to room temperature, peel it off and soak it in ethanol for several times, then dry it in vacuum at 60°C to get the film HKUST-1 @PVDF.

[0030] The structure of the obtained HKUST-1@PVDF film material was analyzed by X-Ray powder diffraction (PXRD) ( figure 1 ); use scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM) to analyze the size, morphology and microstructure of the obtained thin film HKUST-1@PVDF material, and use SEM to calculate the HKUST -1 is about 64nm in diameter.

Embodiment 2

[0032] The preparation process and steps in this example are basically the same as the above-mentioned Example 1, the difference is: the polymer used in this example is PVC, see figure 2 .

Embodiment 3

[0034] The preparation process and steps in this example are basically the same as those in Example 1 above, except that the polymer used in this example is PMMA, see image 3 .

Abstract

The invention discloses a method for synthesizing a metal organic framework material macromolecule polymer film. The method comprises the following steps: sequentially adding a metal salt solution and an organic ligand solution in a macromolecule polymer solution, performing uniform mixing and then scraping the mixture on a substrate, then performing heating, peeling off a film after natural cooling, performing soaking, and performing drying to obtain the metal organic framework material macromolecule polymer film. Compared with a conventional preparation method, the method adopts a simple in-situ reaction method, polymer film materials loaded with different metal organic framework materials can be obtained by a scraping method, and the method has the advantages of simple process, convenient operation, being suitable for mass production, and the like.

Description

technical field [0001] The invention relates to a method for synthesizing a metal-organic framework material polymer film, and belongs to the technical field of metal-organic framework material preparation. Background technique [0002] Metal-organic frameworks (Metal-Organic Frameworks, referred to as MOFs), as a class of porous materials obtained from metals or metal clusters and organic ligands, have high specific surface area, regular channels and good structural tunability. Etc. In recent years, it has shown very promising application prospects in gas storage / separation, catalysis, sensing, and pollutant treatment. However, as a class of porous crystalline materials, MOFs are easily broken into smaller particles or powders during use. And this will be a major problem in practical applications. For example, in industrial processes such as catalysis and separation, these small particles or extremely fine dust produced by the fragmentation of MOFs crystals can easily blo...
