Embodiment 1

[0065] Example 1 Controllable preparation of rare earth phosphate nanoparticles with different shapes and sizes

[0066] 10 milliliters of 0.1mol / L lanthanum nitrate (La(NO 3 ) 3 ) solution was added to 10 ml of water, stirred and mixed. Another 2 mmol of citric acid was added to the solution, and vigorous stirring was continued for 30 minutes. Add 1 mmol of sodium dihydrogen phosphate (NaH 2 PO 4 ), and stirred for another 40 minutes. The solution was then transferred to a hydrothermal kettle and sealed. Heating to 150 degrees Celsius in an oven for 20 hours. After the hydrothermal kettle after the reaction was cooled to room temperature, a white precipitate could be obtained. The samples were centrifuged, washed, and finally dried in a vacuum oven at 60°C overnight. Finally got LaPO 4 Nanoparticles.

[0067] 8 milliliters of 0.1mol / L lanthanum nitrate (La(NO 3 ) 3 ) solution and 2 ml of 0.1mol / L terbium nitrate (Tb(NO 3 ) 3 ) into 10 ml of water, and stir to mi...

[0074] Example 2 Dispersion of Rare Earth Phosphate Nanoparticles in Trimethylolpropane Trimethacrylate Monomer and Its Free Radical Polymerization

[0075] A certain amount of La obtained in Example 1 0.5 Tb 0.5 PO 4 Nanoparticles were added to 300 microliters of organic solvent tetrahydrofuran, and the solution was stirred for 50 minutes under airtight conditions, and then ultrasonically dispersed for 30 minutes to form a dispersed nanoparticle solution. Under vigorous stirring, 1 ml of trimethylolpropane trimethacrylate monomer was added dropwise and ultrasonicated for 60 minutes to obtain a stable nanoparticle polymer monomer solution. A certain amount of benzoyl peroxide compound is added to the solution, and ultrasonic waves are used for 10 minutes to dissolve the benzoyl peroxide and form a stable solution. Next, fill the obtained mixed solution into a suitable glass mold, then put it in a vacuum oven, and remove the organic solvent tetrahydrofuran in the solution at...

[0077] Example 3 Dispersion of rare earth phosphate nanoparticles in methyl methacrylate monomer and its free radical polymerization.

[0078] A certain amount of La obtained in Example 1 0.5 Tb 0.5 PO 4 Nanoparticles were added to 300 microliters of organic solvent tetrahydrofuran, and the solution was stirred for 50 minutes under airtight conditions, and then ultrasonically dispersed for 30 minutes to form a dispersed nanoparticle solution. Under vigorous stirring, 1 ml of methyl methacrylate monomer was added dropwise, and ultrasonicated for 60 minutes to obtain a stable nanoparticle polymer monomer solution. A certain amount of azobisisobutyrocyanide compound is added to the solution, and the azobisisobutyrocyanide compound is ultrasonicated for 10 minutes to dissolve the azobisisobutyrocyanide compound and form a stable solution. Next, fill the obtained mixed solution into a suitable glass mold, then put it in a vacuum oven, and remove the organic solvent tetrahydrofur...

Abstract

The invention discloses a preparation method of a polymer nanocomposite optical material, wherein the method particularly includes three steps: synthesis of nanoparticles with specific optical properties, dispersion of the nanoparticles in polymer monomers, and mass polymerization of the nanoparticles in the polymer monomers. The invention aims to overcome the deficiencies in the prior art that construction cost is high, a preparation process is relatively complicated and crystals with good optical quality are difficult to get, and provides the preparation method simple in preparation process, convenient to operate, low in cost, wide in applicability and friendly to the environment. The polymer nanocomposite optical material obtained by the method can greatly expand the material selection range of optical materials, and also provides an idea for the study on nanomaterials as bulk-phase optical materials. The novel optical material can show attractive application prospects in the fields of modern laser technology, optical communication, data storage, optical information processing and the like.

Description

technical field [0001] The invention relates to an optical material and a preparation method thereof, in particular to a polymer nanocomposite optical material and a preparation method thereof. Background technique [0002] Optical materials are one of the most important materials in modern society and modern technology. The synthesis and research of optical materials is an important part of material science. Among them, electro-optic materials, laser materials, photorefractive materials, and nonlinear optical materials have also received more and more attention. At present, most widely used optical materials are inorganic or semiconductor materials.
