Example Embodiment
[0042] Example 1
[0043] 10 parts of poly-N-isopropyl methacrylamide (molecular weight = 200,000 g / mol), 20 parts of sodium polyacrylate (molecular weight = 500,000 / g / mol), 1 part of 2-hydroxy-4-methoxy- 5-Sulfobenzophenone, 1 part 1-(2'hydroxyethyl)-2,2,6,6-tetramethyl-4-piperidinol, 15 parts sodium chloride, 3 parts sodium sulfite, 50 A mixture of parts of ethylene glycol, dissolved in water to form a 30% colloidal polymer active material. The prepared polymer colloidal active material was placed between ordinary glasses to make a bionic temperature-controlled responsive smart composite glass, the thickness of the polymer colloidal active material was 1 mm. The response temperature of the prepared bionic temperature-controlled and responsive intelligent composite optical glass is 21 0 C. Under 20 0 At C, the light transmittance at the wavelength of UV 200~380nm is less than 0.5%, and the light transmittance at the wavelength of 380~2500nm is greater than 74%; when the temper...

[0046] Example 3
[0047] 20 parts of polyoxypropylene (molecular weight=4000g / mol), 30 parts of polyvinyl alcohol (molecular weight=3 million / g / mol), 1 part of 2,2'-dihydroxy-4,4'-dimethoxy-5 -A compound of sulfobenzophenone, 10 parts of calcium chloride, 3 parts of sodium sulfite, 12 parts of ethylene glycol, and 21 parts of glycerin, dissolved in water to form a 40% colloidal polymer active material. The prepared polymer colloidal active material was placed between ordinary glasses to prepare a biomimetic temperature-controlled responsive smart composite glass. The thickness of the polymer colloidal active material was 2 mm. The response temperature of the prepared bionic temperature-controlled and responsive intelligent composite optical glass is 5 0 C. Under 5 0 At C, the light transmittance at the wavelength of UV 200-380 nm is less than 0.2%, and the light transmittance at the wavelength of 380-2500 nm is greater than 75%; when the temperature is higher than 6 0 At C, the...
