Problems solved by technology

[0005] However, due to the phase separation mechanism caused by the mixing of two incompatible high molecular polymers, the maximum surface roughness (Rmax) of the above-mentioned anti-reflection film is almost equal to the thickness of the anti-reflection film, resulting in the anti-reflection film having Poor mechanical strength and oil resistance

Embodiment 1

[0096] Take a reaction bottle, put 8g (26.82mmol) pentaerythritol triacrylate into the bottle as a multifunctional reactive resin, and dissolve it with 10g tetrahydrofuran (tetrahydrofuran; THF) at a room temperature of 25°C. The ratio is 8wt%. Next, 3.43 g of nematic liquid crystal (nematic liquid crystal, purchased from Merck, code number E7) was added as a template material. After stirring until dissolved, 0.24 g of triphenyl trifluoromethanesulfonate (triphenyl triflate) was added as a photoinitiator, and the preparation of the three-dimensional nanoporous polymer coating composition (A) was completed so far, wherein the resin and the template material The weight ratio is 7:3, and the viscosity of pentaerythritol triacrylate in the three-dimensional nanoporous polymer coating composition (A) is 520 CPS / 25°C. Next, the three-dimensional nanoporous polymer coating composition (A) was coated on a glass substrate with a spin coater, and the rotation speed was controlled at 25...

Embodiment 2

[0099] Proceed in the same manner as Example 1, but reduce the amount of pentaerythritol triacrylate described in Example 1 to 5.6 g, and add 2.4 g of urethane acrylate, so that the polyfunctional The weight ratio of the force resin to the bifunctional acrylic resin is 7 / 3.

[0100] Please refer to image 3 Shown is the SEM image of the three-dimensional nanoporous polymer film formed in Example 2 under the observation of a scanning electron microscope (Scanning Electron Microscope, SEM, model HITACHI S-4200).

Embodiment 3

[0102] Proceed in the same manner as in Example 1, but reduce the amount of pentaerythritol triacrylate described in Example 1 to 4 g, and add 4 g of urethane acrylate, so that the polyfunctional acrylic resin The weight ratio to the bifunctional acrylic resin is 1 / 1.

[0103] Please refer to Figure 5 Shown is the SEM image of the three-dimensional nanoporous polymer film formed in Example 3 under the observation of a scanning electron microscope (Scanning Electron Microscope, SEM, model HITACHI S-4200).

Abstract

The invention provides a 3D nano-porous high-molecular film, having a spongy section, and its preparing method comprises: (a) forming a film layer composed of 3D nano porous high-molecular coating combination on a substrate, where the combination is contained in first solvent; (b) dissolving out the template from the high-molecular layer by second solvent to form it. By filling the air in nano holes uniformly distributed, it can largely reduce effective refractive index to below 1.45, make reflectivity not greater than 3%, and make a contact angle greater than 90 deg. with the water, therefore completely suitable to be used as antireflective or oil rub-resisting coating.

Description

technical field [0001] The present invention relates to a three-dimensional nanoporous polymer film and its manufacturing method, in particular to a three-dimensional nanoporous polymer film with a sponge structure section and anti-reflection and anti-oil pollution capabilities. Background technique [0002] In the manufacturing process of display devices (for example: 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) is provided with an anti-reflection layer. [0003] Anti-reflection optical films with a single-layer structure have gradually become the main research and development trend of anti-reflection technology due to their excellent processing convenience, high yield, high output, and low equipment cost. However, known fl...
