Embodiment 1

[0071] Dissolve 1 part of cobalt chloride hexahydrate, 0.2 part of propylene glycol, 10 parts of triphenylphosphine, 10 parts of tetrabutylammonium bromide, and 1 part of calcium iodide in 50 ml of anhydrous tetrahydrofuran solution. Add 60 parts of polystyrene, 40 parts of dioxane, 1.5 parts of 2,6-di-tert-butyl-p-phenol and 1 part of tin stearate to the solution. Spin-coat the polymer solution on a glass plate to prepare a 0.2 mm thick film. After the dissolution is completely volatilized, another layer of glass is attached to the surface of the film, and kept at 100 degrees and 1 MPa pressure for 20 minutes to prepare a sandwich-structured laminated glass.

[0072] The glass is colorless and transparent under the condition of no sunlight at 20 degrees, and the shading coefficient Se=0.76. Under the condition of 60 degrees without light, Se=0.65. It turns yellow-green under the condition of strong sunlight at 60 degrees, and the shading coefficient Se=0.3.

Embodiment 2

[0074] 0.1 parts of cobalt chloride hexahydrate, 10 parts of 1,3-butanediol, 0.4 parts of triphenylphosphine, 10 parts of tetrabutylammonium bromide, 10 parts of tetrabutylphosphorus bromide, 0.2 parts of silver chloride, Dissolve in 50 mL of anhydrous butyrolactone solution. Add 90 parts of polyvinyl alcohol, 50 parts of dioxane, 0.5 parts of 2,6-di-tert-butyl-a-dimethylamino-p-cresol and 10 parts of tin stearate in the solution to prepare a 20 cm wide 0.4 mm thick film. The prepared film is placed between two pieces of glass, and hot-pressed at 120 degrees and 2 MPa to form a sandwich-structured laminated glass

[0075] The glass is colorless and transparent under the condition of no sunlight at 20 degrees, and the shading coefficient Se=0.72. When there is no light at 60 degrees, Se=0.67. It turns dark green under the condition of strong sunlight at 60 degrees, and the shading coefficient Se=0.28.

Embodiment 3

[0077] Dissolve 2 parts of cobalt chloride hexahydrate, 10 parts of polyvinyl alcohol, 15 parts of triphenylphosphine, 5 parts of ethyltriphenylphosphorus iodide, and 5 parts of calcium iodide in 50 ml of dimethyl adipate solution middle. Add 61 parts of polystyrene in the solution, 60 parts of dioxane, 1 part of 4,4-bis(2,6-di-tert-butylphenol) and 5 parts of dibutyltin maleate, the polymer The solution was spin-coated on a glass plate to prepare a 0.5 mm thick film. Films with a width of 20 cm and a thickness of 0.5 mm were prepared. The prepared film is placed between two sheets of glass, and hot-pressed at 120 degrees and 2 MPa to prepare a sandwich-structured laminated glass.

[0078] The glass is colorless and transparent under the condition of no sunlight at 20 degrees, and the shading coefficient Se=0.74. When there is no light at 60 degrees, Se=0.68. It turns light green under the condition of strong sunlight at 60 degrees, and the shading coefficient Se=0.26.

Abstract

The invention discloses an optothermal response system, an optothermal response resin material prepared by using the optothermal response system as a polymer processing aid, and optothermal response smart glass. The system is obtained by mixing transition metal ions, a polyhydric alcohol ligand compound, a light-sensitive halide and an organic nitrogen compound and / or a phosphorus compound and then performing conformational transition on the mixture by use of an organic transition metal compound. The optothermal response system has double response to light and heat, and is capable of autonomously changing in intensity of color and light transmissivity according to the change of the environment temperatures and the light intensity. The optothermal response resin material has a wide application prospect in the fields such as glass curtain walls, building door and window glass, automobile glass and agricultural greenhouse films. The optothermal response smart glass has relatively high shading coefficient in seasons of relatively low temperatures, and is capable of automatically reducing the shading coefficient in hot high-temperature summer with strong sunlight, and thus has the advantages of complete ultraviolet shielding, low heat conduction efficiency and autonomous sunlight shading coefficient change.

Description
