preparation example Construction

[0041] The invention provides a UV-curable silver nanowire ink, a preparation method and a use method thereof, that is, a one-step method is used to prepare a transparent conductive film with a certain pattern. The present invention prepares a silver nanowire ink containing a UV-curable epoxy resin mixture, and then forms a thin film of the ink on a transparent substrate through a one-step method, and removes the ink in the uncured area after selective UV irradiation, thereby forming a silver nanowire ink with A transparent conductive film with a specific pattern. The UV-curable epoxy resin mixture can be selectively cured according to the pattern requirements, and the one-step method greatly simplifies the production process of the silver nanowire transparent conductive film, and has good practical application value. The present invention is described in detail below:

Abstract

The invention provides a UV curing silver nanowire ink, a preparation method and an application method thereof, namely a transparent conductive film with certain patterns is prepared by the application of one-step method. According to the invention, a silver nanowire ink containing a UV curing epoxy resin mixture; then, the ink forms a film on a transparent substrate by one-step method; the film undergoes selective UV irradiation and uncured ink is removed so as to form the transparent conductive film with specific patterns. Selective curing of the UV curing epoxy resin mixture can be accomplished according to pattern requirements; in addition, the production technology of the silver nanowire transparent conductive film is greatly simplified by one-step method. Therefore, the invention has a great practical application value.

Description

technical field [0001] The invention relates to silver nanowire ink and its preparation method and use method, in particular to the preparation of UV-curable silver nanowire ink and its application to prepare a transparent conductive film with a certain pattern. Background technique [0002] Transparent conductive film refers to a conductive film coated on a surface or substrate with high light transmission. It has good optical transparency and surface conductivity at the same time, and is widely used in products such as liquid crystal displays, touch screens, LEDs, and thin-film solar cells. [0003] At present, indium tin oxide (ITO) thin films prepared by vacuum evaporation chemical deposition process have become the most widely used materials due to their excellent optical transparency and electrical conductivity. However, the ITO film is brittle and easily damaged when subjected to bending, which severely limits its application on flexible substrates. In addition, the...
