Embodiment Construction

[0053] The technical solutions of the present invention will be further described in detail below through examples. The scope of the present invention is not limited by the specific embodiments but by the scope of the claims.

[0054] The spiropyrans according to the present invention can be prepared according to the following steps, with R 1 for hydrogen, R 2 for nitro, R 3 for -CH 2 CH 2 COOH as an example. Add 3.2g of trimethylindole and 4.0g of ioformic acid into a 50mL round bottom flask, protect with nitrogen, heat at 95°C and stir for 4h. After the reaction is complete, the resulting solution is dissolved in 100mL of distilled water, extracted with chloroform, and the organic phases are combined. After rotary evaporation, the residue was recrystallized from acetone-ether to obtain a light yellow solid.

[0055] Weigh 3.6g of the above-mentioned light yellow solid and 1.7g of 5-nitrosalicylaldehyde, 30mL of butanone, and 1mL of piperidine, and reflux for 5h under a...

Abstract

The present invention discloses a photothermally responsive smart energy saving composite film, and is comprised of a reversible photochromism containing a spiropyran material and a vanadium dioxide based reversible thermochromism material. The smart energy saving composite film can be used to prepare one or more layers of alternating and composite color-changeable films, and is both decorative and functional, which is suitable for the requirement of energy saving in architecture and can be widely used in spheres like doors and windows of buildings and energy-saving and safe glasses of cars as well as agricultural green house films. The smart energy saving composite film is based on the photothermal response technology, has a good color changing effect, a good anti-aging property and good stability, can reduce the energy consumption and carbon emission, and has a wide market prospect.

Description

technical field [0001] The invention belongs to the field of intelligent optical composite materials, and relates to a photothermal responsive intelligent energy-saving composite film. 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 predict...
