Problems solved by technology

[0003] During the synthesis of silver nanowires, the ethylene glycol solution needs to be heated to remove the water in it. At the same time, after the water is removed from the ethylene glycol solution, it needs to be placed for later use, so that it can be fused with the subsequent steps. , but the quality of the ethylene glycol solution in the back-end steps has strict requirements, so it is easy to make the demand for the ethylene glycol solution too much or not enough, so it is necessary to remove the water from the ethylene glycol solution again, and then make a backup. And when the ethylene glycol solution is prepared too much, it will also cause waste;

Embodiment 1

[0046] like figure 1 As shown, the present invention is a method for rapidly preparing nano-silver wires, comprising the following steps:

[0047] Step 1, the ethylene glycol solution is placed in the placing container 5, and then the heating pad 3 at the lower end is heated to remove the moisture in the ethylene glycol solution;

[0048] Step 2, FeCl 3 ·6H 2 O and CuCl 2 ·2H 2 O is dispersed in the ethylene glycol obtained through step 1 pretreatment respectively and stirred;

[0049] Step 3, the polyvinylpyrrolidone is dispersed in the ethylene glycol solution and stirred, and sodium dodecylbenzenesulfonate is added;

[0050] Step 4, AgNO 3 Disperse and stir in the ethylene glycol solution obtained by the pretreatment in step 1;

[0051] Step 5, the FeCl gained in step 2 3 ·6H 2 Glycol solution of O and CuCl 2 ·2H 2 The ethylene glycol solution of O is added to the mixed solution of polyvinylpyrrolidone and sodium dodecylbenzenesulfonate obtained in step 3, then p...

Embodiment 2

[0053] like Figure 2-7 As shown, a device for rapidly preparing nano-silver wires includes a base 1, an upper end of the base 1 is fixedly mounted with a jacket 2, and a container 5 is arranged inside the jacket 2;

[0054] A heating pad 3 is fixedly installed on the upper end of the base 1, a limit ring 4 is fixedly installed on the upper end of the heating pad 3, and the container 5 is placed in the limit ring 4;

[0055] A limiting plate 22 is welded on the inner wall of the outer casing 2 , and a sliding frame 23 is arranged on the limiting plate 22 .

Abstract

The invention relates to the technical field of silver nanowire preparation, and discloses a method and device for rapidly preparing silver nanowires, and the method comprises the following steps: 1, placing an ethylene glycol solution in a placing container, and then heating a heating pad at the lower end to remove moisture in the ethylene glycol solution; step 2, respectively dispersing FeCl3. 6H2O and CuCl2. 2H2O into the ethylene glycol obtained by the pretreatment in the step 1, and stirring; 3, dispersing polyvinylpyrrolidone in an ethylene glycol solution, stirring, and adding sodium dodecyl benzene sulfonate; and step 4, dispersing AgNO3 in the ethylene glycol solution pretreated in the step 1, and stirring. By arranging the built-in rotating plate, an ethylene glycol solution at the lower end of the built-in rotating plate is in close contact with a heat source for a period of time, so that the ethylene glycol solution is heated more easily, internal moisture is evaporated more quickly, the required requirement is met, and water vapor in the ethylene glycol solution is lost more quickly to meet the required requirement.

Description

technical field [0001] The invention relates to the technical field of nano-silver wire preparation, in particular to a method and a device for rapidly preparing nano-silver wires. Background technique [0002] Nano-silver wire is a one-dimensional structure of metallic silver with a diameter at the nanometer scale. Due to its small volume and large specific surface, it has good chemical and catalytic properties, as well as excellent antibacterial properties and biocompatibility. It plays an important role in the fields of biomedicine, antibacterial and optics; [0003] In the process of synthesizing the silver nanowires, the ethylene glycol solution needs to be heated to remove the moisture in it. At the same time, after the ethylene glycol solution has removed the moisture, it needs to be placed for later use, so that it can be fused with the following steps. , but the quality of the ethylene glycol solution in the back-end step has strict requirements, so it is easy to m...
