Description

Technical Field

[0002] Currently, functional films that block light and provide heat insulation are commonly found on car windows, glass curtains, and house windows. These films can utilize sunlight for illumination while reducing the amount of ultraviolet and infrared radiation from sunlight on the inside of the glass, as well as regulating the brightness of sunlight on the inside of the glass. Traditional glass films used to reduce ultraviolet and infrared radiation from sunlight and regulate the brightness of sunlight generally use tinted or dark films. However, this approach only allows for the selection of films with a certain color scale. Lighter colors are not effective, while darker colors can affect visibility. Therefore, heat-insulating window films have emerged that can automatically change color based on the brightness of sunlight. While these films can achieve a certain degree of heat insulation while also providing a certain degree of heat insulation, they are poor in safety and explosion-proof performance. Therefore, there is an urgent need to design explosion-proof window films that provide safety and explosion-proof properties to prevent glass shards from splashing and injuring people nearby when the glass breaks.
