Photothermally responsive smart energy saving composite film

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.
