Embodiment 1

[0062] Embodiment 1: Preparation of transparent high hardness anti-scratch coating on glass or monocrystalline silicon substrate

[0063] a. Substrate treatment: The treatment method for the selected solid substrate glass or single crystal silicon wafer substrate is as follows: use toluene, acetone, chloroform, ethanol and distilled water to ultrasonically treat for 10 minutes respectively to remove various impurities attached to the surface of the substrate, and then 98%H 2 SO 4 and 30% (mass concentration) H 2 o 2 (v:v=7:3) in the mixed solution and heated to boil (30min) until no bubbles overflowed. After cooling, rinse with a large amount of distilled water, then blow dry with nitrogen, and set aside. The surface of such treated glass or quartz substrate contains a large amount of silanol; soak the treated glass or silicon wafer substrate in 1mg / mL polydimethylallyl ammonium chloride (PDDA) for 30min to make its surface undergo self-assembly A layer of positively char...

[0074] Embodiment 2: Preparation of transparent high hardness scratch-resistant coating on azobenzene polymer multilayer film

[0075] The treatment of the glass substrate is the same as in Example 1. First, the glass sheet whose surface is modified with polydiallyldimethylammonium chloride PDDA is subjected to the following operations: (1) it is immersed in a concentration of 0.5mg / mL containing The polyelectrolyte (PAC-azoBNS, which is a purple-red dye with a nitrogen phenyl group, the chemical structural formula is shown below, see the literature for the synthesis method: Langmuir 2006, 22, 7894.) in the solution for 20 minutes, and after 3 minutes and 2 minutes , 1 minute three-step deionized water rinse; (2) and then immersed in the prepared 1mg / mL polydiallyl dimethyl ammonium chloride PDDA solution for 20 minutes, take out after 3 minutes, 2 minutes, 1 minute The three-step deionized water rinse; repeat the above two processes (1) (2) for 15 cycles to obtain (PAC-azoBNS...

Embodiment 3

[0079] a. The substrate is made of metal aluminum sheet, which is ultrasonically treated with toluene, acetone, chloroform, ethanol and distilled water for 10 minutes respectively to remove various impurities attached to the surface of the substrate, then rinsed with a large amount of distilled water, and then blown dry with nitrogen, ready for use . Soak the treated aluminum sheet in 1 mg / mL polydimethylallyl ammonium chloride (polydiallyldimethylammonium chloride PDDA) for 30min to modify the surface with a positive layer by self-assembly. Charged quaternized amino groups, such modified aluminum flakes can be used for the preparation of layered assembled membranes based on electrostatic forces.

[0080] b. Preparation of building block solution

[0081] (1) The building block with a negative charge is polyacrylic acid-calcium carbonate (CaCO 3 ) composite solution, its configuration method is as follows: first prepare 60mL monomer concentration is the polyacrylic acid aque...

Abstract

The invention relates to a constructed elementary solution with negative charge, an anti-scratch coating prepared by the constructed elementary solution, and a preparation method for the constructed elementary solution and the anti-scratch coating. The constructed elementary solution is a complex solution comprising weak polyanions, calcium ions and carbonate ions. The preparation method of the anti-scratch coating is as follows: leading amino, carboxyl or hydroxide radical to the surface of substrates, alternatively placing the substrates in the constructed elementary solution and the weak polycations aqueous solution, utilizing a laminated assembly technology to prepare laminated assembly film coating with controllable thickness, and finally carrying out thermal treatment on the obtained coating under 80-250 DEG C for 0.5-20h to obtain the transparent anti-scratch coating with high hardness. The coating can be used as the anti-scratch coating of other functional film materials, has the characteristics of low cost, simple method and no need of complex apparatuses and devices. The size of the coating is not limited by the shape and size of the substrates, therefore, the coating isexpected to have wide application in daily production and life.

Description

technical field [0001] The invention belongs to the technical field of anti-scratch coatings, and in particular relates to a negatively charged building element solution, an anti-scratch coating prepared from the building element solution, and a preparation method thereof. Background technique [0002] Existing studies have shown that polymer-inorganic nanocomposites can exhibit excellent mechanical properties. The mechanical properties of the composite material are closely related to the degree of dispersion of the inorganic nanofillers. The better the dispersion of the inorganic nanofillers, the greater the mechanical properties of the composite material can be enhanced. However, nano-scale inorganic fillers are easy to aggregate due to their large surface energy, so how to realize the uniform dispersion of inorganic nano-fillers in polymer materials is an important issue in the field of mechanical property modification of polymer-inorganic nanocomposites. The existing me...
