Problems solved by technology

[0004] Nowadays, laminated structure barrier film products have become a research and development hotspot, and the types and molecular structures of organic layer materials are also constantly evolving, but usually aiming at improving the gas barrier properties of products; There is no obvious improvement in light rate, chromaticity and other aspects, especially the interlayer adhesion of inorganic / organic barrier layers is often insufficient; and it must reach 10 -4 g / m 2 .day -1 Or lower water vapor permeability (WVTR), generally requires the preparation of multiple organic / inorganic laminated structure (paired layer) barrier layers to achieve, the process is complicated, the cost is high, and the efficiency is low
In addition, the preparation methods of the organic layer usually include three methods: coating method, vacuum coating, and flash evaporation. Among them, the vacuum evaporation and flash evaporation methods are dry film-forming processes. The vacuum coating equipment is expensive, the preparation process is complicated, and it is difficult for industrial production.

Description

technical field [0001] The invention relates to the technical field of thin films, in particular to a coating solution for preparing a functional coating of thin films. Background technique [0002] In order to prevent items from deteriorating due to water and oxygen, gas barrier films can be prepared by evaporating and coating materials with high gas barrier properties on the surface of plastic films. Different application fields have different requirements for gas barrier properties. With the development of technology in recent years, the comprehensive performance requirements of users for barrier films have also been continuously improved. Generally, vacuum-evaporated inorganic barrier layers (silicon oxide, silicon oxynitride, aluminum oxide, etc.) inevitably have defects such as pinholes, and are prone to microcracks due to high brittleness, resulting in reduced barrier properties. [0003] Arranging an organic functional layer (organic barrier layer) before and after ...
