Embodiment 1

[0025] Octapropylaminosilsesquioxane (2.2 g, 2.5 mmol) and citric acid (0.72 g, 3.75 mmol) were weighed, dissolved in 10 mL of deionized water, and stirred until completely dissolved. Transfer the resulting mixed solution to a 25 mL polytetrafluoro-lined reaction kettle, and screw it tightly to make it completely sealed. The reaction kettle was placed in an oven at 180° C., and reacted for 5 hours. Then the reactor was taken out and naturally cooled to room temperature to obtain a pale yellow transparent Si-CPDs aqueous solution. Filter the obtained Si-CPDs aqueous solution with a 0.22 μm polyethersulfone filter membrane to obtain Si-CPDs solidified solution 1, which can be directly coated and solidified, or can be freeze-dried to obtain a dry powder for storage. When ready to use, redissolve in water to cure the coating film.

[0026] Slides were plasma-treated (3 min) to make the surface hydrophilic. Take Si-CPDs curing solution 1, evenly spread it on the surface of the g...

Embodiment 2

[0029] Octapropylaminosilsesquioxane (2.2 g, 2.5 mmol) was weighed. Citric acid (0.48g, 2.5mmol), dissolved in 10mL of deionized water, stirred to dissolve completely. Transfer the resulting mixed solution to a 25 mL polytetrafluoro-lined reaction kettle, and screw it tightly to make it completely sealed. The reaction kettle was placed in an oven at 180° C., and reacted for 5 hours. Then the reactor was taken out and naturally cooled to room temperature to obtain a pale yellow transparent aqueous solution of carbonized polymer dots. Filter the obtained Si-CPDs aqueous solution with a 0.22 μm polyethersulfone filter membrane to obtain Si-CPDs solidified liquid 2; perform the coating film curing according to the operation of Example 1, and obtain the cured film 2, and the performance data are shown in Table 1 .

Embodiment 3

[0031] Octapropylaminosilsesquioxane (2.2 g, 2.5 mmol) was weighed. Citric acid (0.145g, 0.8mmol), dissolved in 10mL of deionized water, stirred to dissolve completely. Transfer the resulting mixed solution to a 25 mL polytetrafluoro-lined reaction kettle, and screw it tightly to make it completely sealed. The reaction kettle was placed in an oven at 180° C., and reacted for 5 hours. Then the reactor was taken out and naturally cooled to room temperature to obtain a pale yellow transparent aqueous solution of carbonized polymer dots. The obtained carbonized polymer dot aqueous solution was filtered with a 0.22 μm polyethersulfone filter membrane to obtain Si-CPDs solidified solution 3; the coating film was solidified according to the operation of Example 1, and the obtained solidified film 3 was obtained. The performance data are shown in the table 1.

Abstract

The invention relates to an ultra-hard wear-resistant transparent film layer material compounded on the nanometer scale with silicon-doped carbonized polymer dots as building blocks and a preparation method thereof, belonging to the technical field of preparation of super-hard wear-resistant scratch-resistant transparent film materials. It is to weigh propylaminosilsesquioxane and citric acid with a molar ratio of 1:0.1~4 and dissolve them in deionized water, then hydrothermally react at 160~200°C for 3~8 hours; then cool naturally to room temperature to obtain light The yellow and transparent Si-CPDs aqueous solution is filtered with a 0.22 μm polyethersulfone filter membrane to obtain a Si-CPDs solidified solution containing silicon hydroxyl groups on the surface; the solidified solution is spin-coated, dip-coated or spray-coated on Plasma for 3-5 minutes The surface of the glass slide is cured at 60-200° C. for 0.5-3 hours, so as to obtain the superhard wear-resistant transparent film layer of the present invention. The film layer material can be used to prepare the surface hard wear-resistant protective layer of displays, transparent optical devices and solar cells.

Description

technical field [0001] The invention belongs to the technical field of preparation of super-hard wear-resistant and scratch-resistant transparent film materials, and specifically relates to a super-hard wear-resistant transparent film material compounded on the nanometer scale with silicon-doped carbonized polymer dots as building blocks and its According to the preparation method, the film layer material can be used for the surface hard wear-resistant protective layer of displays, transparent optical devices and solar cells. Background technique [0002] Optical coatings have a wide range of applications in displays, transparent optical devices, and solar cells. Optical coatings can be divided into two broad categories: polymeric optical coatings and inorganic optical coatings. Polymer optical coatings have the advantages of light weight, impact resistance, and easy processing and molding, but the polymer has low surface hardness and poor wear resistance. Inorganic optica...
