Flexible sunshading film

Abstract

The invention discloses flexible sunshading film. The flexible sunshading film comprises a flexible transparent sunshading composite layer used for controlling the light ray transmittance; the flexible transparent sunshading composite layer comprises a transparent flexible anode layer, a transparent flexible cathode layer and a sunshading layer arranged between the transparent flexible anode layer and the transparent flexible cathode layer, and the sunshading layer is used for achieving transparency or nontransparency under control of voltage. According to the flexible sunshading film, the transparent flexible anode layer and the transparent flexible cathode layer are arranged, the light ray transmittance is controlled by the sunshading layer, and then the light ray transmittance of the flexible sunshading film is adjusted; when the voltage is applied, the flexible sunshading film is in a transparent state to not shield light, at the moment, the transmittance is very high and can reach 90% or above, and opulent sunshine can be achieved; when the voltage is not applied, the flexible sunshading film is in a nontransparent state, sunshading is achieved, outdoor sunshine irradiation can be shielded very well, the sunshading coefficient can be decreased to 0.2, and the sunshading effect can be achieved very obviously; the temperature and brightness in a vehicle or room can be intelligently adjusted.

Description

technical field [0001] The invention relates to the field of optics, in particular to a flexible sunshade film. Background technique [0002] As a material with very good light transmission, glass can effectively improve the light exposure of closed environments such as houses and cars. Since its invention and large-scale application, it has been welcomed by users. However, when it is hot summer, very strong sunlight also shines into the room through the glass, causing the temperature in the room to rise sharply. For most of the large buildings at present, the indoor air conditioning system is often used for temperature adjustment, but this greatly causes a waste of electric energy. In addition, for outdoor parking in summer, the temperature inside the car is often higher than 60 degrees Celsius, which will affect the reliability of the facilities in the car and greatly reduce the comfort; sun visor, but its structure is rigid and cannot be used directly on existing glass...

AI Technical Summary

Problems solved by technology

However, when it is hot summer, very strong sunlight also shines into the room through the glass, causing the temperature in the room to rise sharply.

For most of the current large buildings, the indoor air conditioning system is often used for temperature adjustment, but this greatly causes a waste of electric energy

In addition, for outdoor parking in summer, the temperature inside the car is often higher than 60 degrees Celsius, which will affect the reliability of the facilities in the car and greatly reduce the comfort; sun visor, but its structure is rigid and cannot be used directly on existing glass
