Abstract

The invention relates to an optical film and a manufacturing method of the optical film. The optical film has an anti-reflection self-cleaning function. The manufacturing method of the optical film comprises the following steps of preparing a secondary wavelength microstructure on the surface of a transparent polymeric film to form an anti-reflection optical surface, modifying the surface of the polymeric film by utilizing CF4 plasma to form a hydrophobic functional group structure; obtaining the optical film with the anti-reflection self-cleaning function. The manufacturing method of the optical film disclosed by the invention has the advantages of simple process, repeatability, low cost and capability of meeting requirements of market on anti-reflection self-cleaning products.

Description

technical field [0001] The invention relates to an optical film and a preparation method thereof, in particular to an anti-reflection self-cleaning optical film and a preparation method thereof. Background technique [0002] Optical films have been widely used in various fields of life. Electronic products such as computers, digital cameras, mobile phones, and digital TVs generally use reflective films and diffusion films. In addition, anti-reflection film is often used on the glass of high-rise buildings and automobiles to improve the visual effect and avoid the "dazzling" phenomenon caused by light reflection. Generally speaking, multi-layer anti-reflection film has better anti-reflection effect, however, the more the number of layers will inevitably increase the production cost, and it will also cause the problem of mechanical connection strength between layers, making the production more difficult. [0003] Furthermore, due to the difficulty in cleaning the window glass...
