Abstract

The invention relates to a preparation method of a flexible transparent conductive thin film having a self-cleaning function. The preparation method is characterized by comprising the steps of adding a nanometer silver wire with spherical nanometer silver in a surface into organic silicon resin, simultaneously adding a mercaptyl-terminated fluorine-containing polyether compound, and performing uniform stirring to obtain a mixed liquid, wherein the mass ratio of the nanometer silver wire with the spherical nanometer silver in the surface, the organic silicon resin and the mercaptyl-terminated fluorine-containing polyether compound is 1:(10-50):(0.01-0.05); spraying the mixed liquid obtained in the abovementioned step on a surface of the flexible transparent thin film; and heating the obtained product to 80-120 DEG C, and performing braking for 0.5-2 hours to obtain the flexible transparent conductive thin film having the self-cleaning function. The flexible transparent conductive thin film having the self-cleaning function can be applied to the fields such as a handheld electronic display or a large-size industrial electronic display, and has the advantages of self-cleaning function, high transparency, good flexibility, good adhesive property of a conductive coating layer and the like.

Description

technical field [0001] The invention relates to a preparation method of a flexible transparent conductive film with self-cleaning function. Background technique [0002] In recent years, the rapid development of handheld electronic products, the rapid popularization of large-screen and high-definition liquid crystal displays and the increasing demand have provided huge opportunities and development space for transparent conductive films. Transparent conductive film means that the transmittance of visible light in the wavelength range between 380-780 nm is greater than 80%, and the resistivity is lower than l0 -3 Ω.cm thin film, which has a very broad application prospect and market space. [0003] At present, transparent conductive films are mainly hard transparent conductive materials based on oxide semiconductor films (TCO), among which indium tin oxide (ITO) is the most widely used transparent conductive film in research and application, but ITO raw material resources a...
