Embodiment 1

[0020] A method for preparing a paper-based metal-organic framework with simple process and portability The specific preparation process is as follows:

[0021] (1) Selection of paper base: choose ordinary filter paper or chromatographic paper as the paper base, and cut it into A4 size paper;

[0022] (2) Design the batch printing pattern of hydrophobic wax on the paper base on the computer, the style is as attached figure 1 shown;

[0023] (3) Use wax printing technology to print the hydrophobic wax batch printing pattern designed in step (2) on A4 paper, then take out the paper, place it in an oven, and heat it at 130~150 ºC for 2 minutes to melt the wax And soak through the entire thickness of the paper to form a hydrophobic wall, and the part without printing wax is a hydrophilic area;

[0024] (4) Growth of paper-based metal-organic frameworks:

[0025] The growth of the paper-based metal organic framework comprises the following steps:

[0026] To grow a dense layer ...

Embodiment 2

[0028] The preparation steps are the same as in Example 1, except that the deposition charge in step (5) is 0.05 C.

Embodiment 3

[0030] The preparation steps are the same as in example 1, the difference is: in step (5) CuSO 4 The solution concentration was 10.0 mM, and the deposition charge was 0.01 C.

Abstract

The invention discloses a preparation method of a three-dimensional paper-based metal organic framework, and belongs to the field of preparation of organic nano materials. The method comprises the following steps of selection of a paper base, design of paper-based hydrophobic wax batch printing patterns, electrode printing and paper-based metal organic framework growing. The preparation method of the three-dimensional paper-based metal organic framework has the advantages that due to the fact that paper is selected as the base material, reserves are rich, and the advantages of being easy to fold, convenient to carry and the like are achieved. The preparation technology is simple, the paper-based metal organic framework can achieve on-site instant visual detection easily, and meanwhile a very good foundation is laid for preparation of multifunctional paper-based electronic devices.

Description

technical field [0001] The invention relates to a preparation method of a three-dimensional paper-based metal-organic framework, belonging to the field of preparation of organic nanomaterials. Background technique [0002] Metal-organic framework (MOF) is a crystalline molecular material, which is a structure formed by linking metal ions or metal clusters together through organic ligands. This material has a large internal porosity, and its voids Cavity and chemical properties are adjustable. At present, this material has been well applied in the fields of gas storage, chemical separation, catalysis, optical imaging and sensing. [0003] A class of MOF materials based on iron porphyrin has been widely used in colorimetric and electrochemical biosensors due to its good enzyme-like catalytic properties, and has realized the detection of different types of molecules such as ascorbic acid, hydrogen peroxide, and metal ions. . The preparation process of general MOF materials i...
