Embodiment 1

[0076] 1 kg of zinc oxide particles with a particle size of 5 nanometers, 3 kg of pentaerythritol, and 15 kg of dioxane were ground for two hours with a sand mill of zirconia particles with a particle size of 0.3 mm to obtain surface polyol-modified nano Zinc oxide solution.

Embodiment 2

[0078] 50 grams of tungsten oxide particles with a particle diameter of 20 nanometers were dispersed in 2 liters of absolute ethanol solution, and 5 milliliters of hydroxypropyltriethoxysilane was added. React under vigorous stirring for 24 hours, then centrifuge to remove ethanol. The dried surface-modified nano-tungsten oxide was dispersed into 2L dimethyl glutarate solution through a sand mill. The hydroxyl content was 2 mol / kg.

Embodiment 3

[0080] 100 grams of alum pentoxide nanoparticles with a particle diameter of 500 nanometers were dispersed in 2 liters of absolute ethanol solution. Slowly add 20 ml of chlorobenzyltriethoxysilane under stirring condition. The reaction was carried out under vigorous stirring for 24 hours. The reaction solution was passed through nitrogen to remove oxygen for 20 minutes, and then 20 grams of cuprous chloride, 10 grams of bipyridine and 200 grams of hydroxyethyl acrylate were added. The temperature of the reaction solution was raised to 70°C, and the reaction was carried out for 2 hours. Centrifuge and dry to prepare 1905 g of surface-grafted vanadium pentoxide nanoparticles with a hydroxyl content of 5 mol / kg.

Abstract

The invention discloses a nano-composite optothermal response system, a resin material and smart glass.The system is formed in the mode that after transition metal ions, alpha or beta alcoholic hydroxyl surface-modified heat-absorption nano materials, halide and organic nitrogen compounds and / or phosphorus compounds are mixed, the nano materials are subjected to optothermal conversion, and organic transition metal complexes are subjected to conformation conversion.The system can respond to both light and heat, and the color and the light transmissivity are autonomously changed according to changes of environment temperature and light intensity.The optothermal response resin material has wide application prospects in the fields of glass curtain walls, building door and window glass, automobile glass, agricultural greenhouses and the like.The optothermal response smart glass has a high shading coefficient in low-temperature seasons, the shading coefficient can be automatically reduced in burning-hot, high-temperature and strong-sunshine summer, and the advantages that ultraviolet rays are completely shielded, the heat conduction efficiency is low and the sunlight shading coefficient autonomously changes are achieved.

Description

technical field [0001] The invention belongs to the field of intelligent optical materials, and relates to a nanoparticle photothermal response system, a resin material, and intelligent energy-saving glass. Background technique [0002] Smart material refers to a composite material that imitates a living system, can perceive environmental changes, and can adjust or change the performance parameters of the material itself in time according to the perceived environmental parameters, and make expected changes that can adapt to the changed environment. Combination of materials. Life-like sensation and self-regulation are important features of smart materials. [0003] With the development of the times, the intelligent construction of building materials has become more and more in-depth. The content and meaning of intelligent buildings have been continuously extended with the development of science and technology, and their functions have also been continuously expanded to meet ...
