Intelligent energy saving composite film

Abstract

The invention discloses an intelligent energy saving composite film. The intelligent energy saving composite film comprises a PET thermal-reflective film layer, at least one near infrared absorption film layer, and at least one optothermal responsive film layer; and coating, spraying, bonding, or extruding combination means are adopted for multi-layer alternative combination of the above layers. The intelligent energy saving composite film is high in intelligent performance, is capable of adjusting shielding coefficient and light transmittance through automatic generated stress-coping behaviors based on external environment change, realizing composite film color change in a set temperature or light intensity range, realizing intelligent adjusting on environment temperature and light, realizing preferable utilization and shielding of solar energy, maintaining environment stability, improving environment comfortableness, reducing energy consumption, and saving energy.

Description

technical field [0001] The invention relates to the technical field of optical composite materials, in particular to an 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 predictions show that in the m...

Problems solved by technology

Smart glass made of traditional silver halide is expensive, heavy, poor glass strength, poor discoloration effect, short life, and difficult to guarantee stability

Especially when used as architectural glass, in the cold and low temperature winter, people need high sunlight transmittance to meet indoor heating and reduce energy consumption. Therefore, silver halide smart glass cannot meet people's needs as smart sunshade glass
