Problems solved by technology

However, in this method, heat treatment will cause greater damage to the transparent substrate, which will lead to curling of the transparent substrate and a decrease in the light transmittance of the substrate. Changes in shape and performance do not occur from time to time, thereby increasing the cost of raw materials, resulting in a higher cost of the prepared transparent conductive film

Embodiment Construction

[0014] The present invention will be described in further detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0015] like figure 1 As shown, it is a flow chart of the manufacturing method of the transparent conductive film in this specific embodiment, including the following steps:

[0016] 1) Select a transparent substrate, and clean the surface of the transparent substrate material. The transparent substrate can be a copolymer of one or more of glass, polycarbonate, polyester, polyacrylate, polyurethane, or a mixture, or a laminate. Preferably, in this step, a plasma cleaning machine can be used to carry out plasma cleaning on the surface of the transparent substrate material, which can improve the surface state of the transparent substrate, thereby improving the spreadability of the spray solution on the surface of the transparent substrate in subsequent steps, thereby facilitating the uniform spraying of the solution o...

Abstract

The invention discloses a manufacturing method of a transparent conducting film and the transparent conducting film. The manufacturing method includes the following steps that (1) a transparent base is selected, and the surface of the transparent base material is washed; (2) nano silver wire dispersion liquid with the concentration being 0.01-10 mg / mL is prepared; (3) the nano silver wire dispersion liquid prepared in the step (2) is sprayed on the surface of the transparent base material; (4) the nano silver wire dispersion liquid is dried to obtain a nano sliver wire material layer overlaid on the surface of the transparent base material; (5) radio-frequency tubes with the power being 10-5000 W are used for generating plasmas, and plasma treatment is conducted on the nano silver wire material layer for 30 seconds to 30 minutes. According to the manufacturing method, a specific plasma treatment mode is used for treating the nano silver wire material layer, and therefore the electrical conductivity of the transparent conducing film can be improved. Meanwhile, according to the manufacturing method, the washing purification process of nano silver wire raw materials is omitted, high-standard transparent base materials are not needed, therefore, the technology is simple, and the cost is lower.

Description

【Technical field】 [0001] The invention relates to the preparation technology of microelectronic materials, in particular to a method for manufacturing a transparent conductive film and the prepared transparent conductive film. 【Background technique】 [0002] The flexible transparent conductive film using nano-silver wire as the main component has excellent light transmission performance, electrical conductivity and flex resistance in the visible light region, and has been widely used in various display screens and solar cells. In the manufacturing method of existing transparent conductive film, at first will transparent base material be cleaned, also will nano-silver wire raw material be cleaned and purified to remove the residual insulating polyvinylpyrrolidone (PVP) on the surface of the raw material, and then the nano-silver wire raw material is made into After the nano silver wire dispersion liquid is formed, the nano silver wire dispersion liquid is coated on the transp...
