Problems solved by technology

However, since this known antireflective film is completely composed of the condensation product of tetramethoxysilane, the mechanical strength of the film is only derived from the silicon-oxygen-silicon bond (Si-O- Si), and the crosslinking density of the condensate of tetramethoxysilane is not high, resulting in poor mechanical strength and hardness of the antireflection film, resulting in poor abrasion resistance of the antireflection film, which cannot be used Reflective optical coatings for flat panel displays

Abstract

The invention relates to a 3D nano-porous film and the manufacturing method thereof. And the manufacturing method comprises: (a) providing a substrate, which has a precoating surface; (b) forming a film layer composed of 3D nano porous coating combination on the precoating surface; (c) supplying energy to the film layer to making polymerization reaction on the above combination so as to form organic-inorganic mixed layer on the precoating surface; and (d) dissolving out template from the mixed layer by second solvent to form the 3D nano porous film, which has effective refractive index below 1.45 and reflectivity not greater than 3%, and extremely good mechanical strength and rigidity, completely suitable to be used as antireflective and wearable coating for a display unit.

Description

technical field [0001] The invention relates to a three-dimensional nanoporous film and a manufacturing method thereof, in particular to a three-dimensional nanoporous film with high mechanical strength and anti-reflection capability and a manufacturing method thereof. Background technique [0002] In the manufacturing process of display devices (such as: optical lenses, cathode ray displays, plasma displays, liquid crystal displays, or light-emitting diode displays), in order to prevent the image from being disturbed by glare or reflected light, the outermost layer of the display device (such as a transparent substrate of a liquid crystal display) to configure an anti-reflection layer. [0003] Anti-reflection optical films with a single-layer structure have gradually become the main research and development trend in anti-reflection technology due to their excellent processing convenience, high yield, high output and low equipment cost. However, known fluorine-containing i...
