Another example is the Chinese patent application with publication number CN103258865A, which discloses an oxide film substrate, its manufacturing method, photovoltaic cells and organic light-emitting devices including it. This application improves the haze value by forming textures on the oxide film. The application Also limited by the thickness of the oxide, these sub-wavelength scale structures are less effective in improving the transmittance

Abstract

The invention discloses a high haze transparent conductive film and a manufacturing method thereof and relates to the transparent conductive electrode manufacturing field. The transparent conductive film comprises a transparent electrode, wherein one surface of the transparent electrode is coated with a transparent transfer printing medium with a suede surface. The manufacturing method comprises steps that the transparent electrode is made on a substrate, the surface of the electrode is uniformly coated with a transfer printing medium layer, the surface of the electrode coated with the transfer printing medium is made to tightly contact with a texturing template, after solidification, the transfer printing medium is separated from the texturing template, the electrode is separated from thesubstrate, and the high haze transparent conductive film is acquired. The high haze transparent conductive film is advantaged in that the conductive film has high haze, low reflectivity is realized,and stronger light scattering capability is realized, moreover, the haze and a water static contact angle value are adjustable. The manufacturing method is advantaged in that the method is simple andeasy.

Description

technical field [0001] The invention relates to the technical field of preparation of transparent conductive electrodes, in particular to a high-haze transparent conductive film and a preparation method thereof. Background technique [0002] Generally speaking, a transparent electrode means that the transmittance to the spectrum of the incident light wavelength range between 380nm and 780nm is greater than 80%, and the resistivity is lower than 10 -3 Ω·cm film electrode. Transparent electrodes are widely used in optoelectronic devices such as touch screens, displays, electromagnetic shielding, solar cells, and LEDs. At present, the main types of transparent electrodes are: indium tin oxide (ITO) transparent electrodes, carbon nanotube transparent electrodes, graphene transparent electrodes, metal nanowire transparent electrodes, metal grid transparent electrodes, etc. [0003] Haze is a very important performance parameter of transparent conductive film. Haze refers to the...
