Embodiment 1
[0037] This embodiment is used to illustrate the preparation method of the anti-reflection coating of the present invention and the detection of its adhesion.
[0038] To 99.9 g of propylene glycol methyl ether acetate was added 0.1 g of methacryloxysilane-modified silica nanoparticles (Degussa R7200, the primary particle size is 12nm, and the particle size of a single particle on the information given by the manufacturer is 12nm, but because the gas-phase nano-particles are generated by a high-temperature sintering method, they generally exist in micron-scale agglomerations), stirred at 500rpm to obtain a uniform slurry. Ultrasonic cell pulverizer was used to ultrasonically disperse the above slurry for 1 h, and the ultrasonic power was 1200W. Then, use a planetary ball mill to grind the slurry, the diameter of the grinding ball is 0.5mm, the rotation speed is 500rpm, and the grinding time is 12h to obtain a silica nano-dispersion.
[0039] Add 0.8 g of photoinitiator Irga...
Embodiment 2
[0043] This embodiment is used to illustrate the preparation method of the anti-reflection coating provided by the present invention.
[0044] Add 3 g of unmodified aluminum oxide nanoparticles (Degussa AluC, the particle size is 13nm), stirred evenly under 500rpm. Ultrasonic cell pulverizer was used to ultrasonically disperse the above slurry for 1 h, and the ultrasonic power was 1200w. Then, use a planetary ball mill to grind the slurry, the diameter of the grinding ball is 0.5 mm, the rotation speed is 500 rpm, and the grinding time is 12 hours to obtain a nano-dispersion of aluminum oxide.
[0045] The above nano-dispersion liquid was flow-coated on the PMMA substrate, the substrate was put into an oven, and baked at 80° C. for 0.5 h to obtain an anti-reflection coating.
[0046] On the other surface of the PMMA substrate, an antireflection coating was obtained in the same manner.
Embodiment 3
[0048] This embodiment is used to illustrate the preparation method of the anti-reflection coating provided by the present invention.
[0049] Add 0.3 g of acrylate DESMOPHEN A450 BA (Bayer) to 72 g of absolute ethanol and 24 g of propylene glycol methyl ether acetate, and stir evenly at 500 rpm. Then add 3 g unmodified silica nanoparticles (Degussa A200, the particle size is 12nm), stirred at 500rpm to obtain a uniform slurry. Then, ultrasonically disperse the above slurry for 1 h using an ultrasonic cell pulverizer with an ultrasonic power of 1200w to obtain a silica nano-dispersion. Add 0.066g thermal initiator DESMODUR N3390 BA / SN (Bayer) to the prepared silicon dioxide nano-dispersion liquid, stir at 500rpm to make it dissolve completely.
[0050] Use an inkjet printer (Fujifilm Dimatix Materials printer Dmp-2831) to spray the above solution on a PET substrate (substrate thickness is 0.188mm), put the substrate in an oven, and bake it at 80°C for 8h to obtain an anti-r...
