Problems solved by technology

However, if this kind of glass is kept at a temperature higher than the critical point for a long time, the temperature-sensitive polymer will precipitate and it is difficult to restore the original state, so that the smart glass does not have the function of repeated use.
Another temperature-sensitive smart glass is formed by placing network structure polymers prepared by polyisopropylacrylamide between glasses. However, polyisopropylacrylamide colloids will shrink when the temperature is higher than the critical temperature for a long time, and Pushes out absorbed moisture, making the glass less environmentally stable and difficult to reuse
At present, there is no smart optical composite glass material with a working range of -20 to 80°C and an outdoor service life of 5 to 10 years

Abstract

The invention discloses bionic thermostatic response type intelligent composite optical glass, which is formed via arranging active ingredients of polymer colloid capable of producing reversible nano-scale phase separation type temperature responses at the critical temperature between optical glass materials. When the temperature is lower than the critical temperature, the bionic thermostatic response type intelligent composite optical glass has a good light transmission performance (the light transmittance with the ultraviolet wavelength being 200-380nm is less than 1 percent, and the light transmittance with the wavelength being 380-2500nm is more than 60 percent); and when the temperature is higher than the critical temperature, the bionic thermostatic response type intelligent composite optical glass is opaque (the light transmittance with the ultraviolet wavelength being 200-380nm is less than 1 percent, and the light transmittance with the wavelength being 380-2500nm is less than 10 percent. The intelligent composite optical material is formed based on the nano phase separation technology and can be used for 5-10 years continuously and normally at the outdoor temperature of minus 20 DEG C to 80 DEG C, the energy consumption can be reduced, carbon emissions can be reduced, and the material has broad market prospects.

Description

technical field [0001] The invention relates to an intelligent optical composite material, in particular to a bionic temperature control responsive intelligent composite optical 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 buildings will become more and more in-depth. The content and meaning of intelligent buildings will continue to expand with the development of science and technology, and their functions will also continue to expand to meet the growing needs of people. Relevant predic...
