preparation example Construction

[0028] On the one hand, the embodiment of the present invention provides a kind of preparation method of silver nanowire film, such as figure 1 shown, including the following steps:

[0029] S01: Provide the substrate;

[0030] S02: coating the silver nanowire ink on the substrate, performing a first drying treatment, and obtaining an initial silver nanowire film;

[0031] S03: placing the initial silver nanowire film in a mixed gas containing borane complex and water vapor for surface treatment, and then performing a second drying treatment to obtain a silver nanowire film.

[0032] In the preparation method of the silver nanowire thin film provided by the embodiment of the present invention, the silver nanowire ink is coated on the substrate for the first drying treatment, and then placed in a mixed gas containing borane complex and water vapor for surface treatment , in the surface treatment process: (1) First, through the action of borane complex, the -COOH and -COO(CH ...

Embodiment 1

[0048] A method for preparing a silver nanowire film, comprising the steps of:

[0049] S11: Provide PET film;

[0050] S12: coating the silver nanowire ink on the PET film, drying at 130° C. for 1 min to obtain an initial silver nanowire film;

[0051] S13: The initial silver nanowire film is placed in a mixed gas at a temperature of 50°C for surface treatment for 30 minutes. The mixed gas is obtained by heating a mixed solution of dimethylamine borane and water, and dimethylamine borane in the mixed solution is The mass fraction of is 45%, and the balance is water;

[0052] S14: Then dry at 90° C. for 10 minutes to obtain a silver nanowire film.

Embodiment 2

[0054] A method for preparing a silver nanowire film, comprising the steps of:

[0055] S11: Provide PET film;

[0056] S12: coating the silver nanowire ink on the PET film, and drying at 100° C. for 2 minutes to obtain an initial silver nanowire film;

[0057] S13: Place the initial silver nanowire film in a mixed gas at a temperature of 90°C for surface treatment for 30 minutes. The mixed gas is obtained by heating a mixed solution of tert-butylamine borane and water, and the mass fraction of tert-butylamine borane in the mixed solution is 1.5 %, the balance is water;

[0058] S14: Then dry at 100° C. for 2 minutes to obtain a silver nanowire film.

Abstract

The invention belongs to the technical field of nano materials, and particularly relates to a silver nanowire film and a preparation method thereof. The preparation method of the silver nanowire filmcomprises the following steps: providing a substrate; coating silver nanowire ink on the substrate, and carrying out first drying treatment to obtain an initial silver nanowire film; and placing the initial silver nanowire film in a mixed gas containing a borane complex and water vapor for surface treatment, and then performing second drying treatment to obtain the silver nanowire film. The sheetresistance of the silver nanowire film prepared by the preparation method is remarkably reduced, the reliability is extremely good, and the preparation method has the characteristics of simplicity, rapidness and low cost.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a silver nanowire thin film and a preparation method thereof. Background technique [0002] With the development of science and technology, bendable and rollable flexible optoelectronic devices are gradually becoming known to the public, and are considered to have broad application prospects in both consumer and industrial applications. Traditional optoelectronic devices generally use rigid glass substrates such as indium tin oxide (ITO) as transparent electrode materials, which obviously cannot meet the bendable or even rollable requirements of flexible optoelectronic devices. In order to solve this problem, a transparent conductive film of silver nanowires (SilverNanowires, AgNWs) with high conductivity, high light transmittance and foldability is used to replace the ITO electrode. [0003] The production process of the AgNWs film is very simple. After ...
