Abstract

The invention discloses an abrasion-resistant flexible transparent conductive film and a preparation method of the film. The surface of PET is coated with coating, and then the film is prepared after being dried. According to the formula of a sizing material, the sizing material is composed of nanometer silver wires, oleoresin, additive powder, flatting agents and a proper quantity of organic solvents. The nanometer silver wires excellent in electrical conductivity are adopted and nanometer oxide and fiber-phase materials are mixed with the additive powder to serve as additives so that the electrical conductivity and the abrasion resistance of the film can be improved. The abrasion-resistant flexible transparent conductive film is suitable for reel-to-reel continuous production, production efficiency is improved, and transportation is facilitated. The abrasion-resistant flexible transparent conductive film is reasonable in design, simple and low in cost.

Description

technical field [0001] The invention relates to a film, in particular to a wear-resistant flexible transparent conductive film and a preparation method thereof. Background technique [0002] Since the 1960s, transparent conductive films and some other transparent conductive materials have emerged. However, the most widely used transparent conductive film is prepared on hard materials such as glass and ceramics, which has the disadvantages of being brittle, not easily deformed, and heavy, and hard materials such as large-sized glass are not easy to prepare, which limits the transparent conductive film. Applications. In contrast, the flexible transparent conductive film prepared on the organic flexible substrate not only has the same photoelectric characteristics, but also has many unique advantages, such as bendable, unbreakable, light weight, and can be prepared in various sizes, shapes and It can be produced continuously in roll-to-roll mode, which improves production eff...
