preparation example Construction

[0025] see figure 1 , figure 1 It is a schematic diagram of the steps of the preparation method of the acrylamide transparent conductive gel of the present invention. Such as figure 1 As shown, the invention provides a kind of preparation method of acrylamide transparent conductive gel, comprising the following steps:

[0026] Step 1: dissolving acrylamide in deionized water and stirring until the acrylamide is completely dissolved to obtain a first solution;

[0027] In one embodiment, this step can be specifically performed as follows: Weigh 1-10 g of acrylamide, pour 50 ml of deionized water into a beaker, and slowly pour acrylamide into the beaker under the premise of continuous stirring with a magnetic stirring bar in until the acrylamide is completely dissolved to obtain the first solution.

[0028] Step 2: adding lithium acetate, ammonium persulfate, N,N'-methylenebisacrylamide, and tetramethylethylenediamine to the first solution in sequence, and stirring evenly to...

Embodiment 1

[0040] This implementation case shows a preparation method of acrylamide transparent conductive gel according to the following steps:

[0041] Step 1: Weigh 1g of acrylamide, pour 50ml of deionized water into the beaker, and slowly pour the acrylamide into the beaker under the premise of continuous stirring with a magnetic stirrer until the acrylamide is completely dissolved to form the first solution .

[0042] Step 2: Add 5g of lithium acetate, 0.01g of ammonium persulfate, 0.05g of N,N'-methylenebisacrylamide, and 5μL of tetramethylethylenediamine into the first solution in sequence, and continue to stir with a magnetic stirring bar for 3min to The solutes are all dissolved to form a second solution.

[0043] Step 3: Pour the prepared second solution into a 4cm×8cm rectangular template, seal it with a sealed bag, put it in a 90°C oven, and take it out after 10 minutes to obtain a transparent and conductive acrylamide hydrogel.

Embodiment 2

[0045] Step 1: Weigh 4g of acrylamide, pour 50ml of deionized water into the beaker, and slowly pour the acrylamide into the beaker under the premise of continuous stirring with a magnetic stirrer until the acrylamide is completely dissolved to form the first solution .

[0046] Step 2: Add 10g of lithium acetate, 0.5g of ammonium persulfate, 0.05g of N,N'-methylenebisacrylamide, and 30μL of tetramethylethylenediamine into the first solution in sequence, and continue stirring with a magnetic stirrer for 6 minutes to The solutes are all dissolved to form a second solution.

[0047] Step 3: Pour the prepared second solution into a 4cm×8cm rectangular template, seal it with a sealed bag, put it in an oven at 80°C, and take it out after 20 minutes to obtain a transparent and conductive acrylamide hydrogel.

Abstract

The invention discloses a preparation method of acrylamide transparent conductive gel, which comprises the following steps: dissolving acrylamide in deionized water and stirring until the acrylamide is completely dissolved to obtain a first solution; lithium acetate, ammonium persulfate , N, N'-methylenebisacrylamide, and tetramethylethylenediamine were sequentially added to the first solution, stirred evenly to obtain a second solution; the second solution was poured into the template, and then placed Bake in an oven to obtain acrylamide transparent conductive gel. The invention is simple and convenient to operate, and the prepared acrylamide hydrogel has good stretchability and transparency, and the sensor made by the method has high sensitivity, and solves the problems of complex preparation process, long time consumption, opacity, poor conductivity and the like of many traditional methods.

Description

technical field [0001] The invention relates to the technical fields of electronic devices, sensors, medicine and hygiene, and in particular to a preparation method of acrylamide transparent conductive gel. Background technique [0002] Hydrogel is a kind of soft polymer material with a three-dimensional cross-linked network structure and a large amount of water in its structure, which has good water permeability, biocompatibility and biodegradability. Hydrogels are divided into natural hydrogels and synthetic hydrogels; according to their cross-linking structures, they are divided into physically cross-linked hydrogels and chemically cross-linked hydrogels. For now, gel-based sensors are usually dominated by metal nanowire hydrogels and ionic hydrogels. Ionic hydrogels have good conductivity and transparency and are ideal sensor materials. Most ionic hydrogels are gels formed by the interaction of polymers and metal ions. As people attach great importance to the fields o...
