Smart Glass Film

Smart glass film is a specialized thin film material, typically composed of a polymer matrix, with electrochromic properties. It is designed to change its transparency when subjected to an electrical current or voltage, providing controllable optical characteristics. This film can be applied to glass surfaces, effectively transforming ordinary glass into smart glass, and offering features such as privacy protection, light modulation, and energy conservation.

Principle

The working principle of smart glass film is based on electrochromic technology. Within this film, typically contained are molecules or particles with specific structures. When an electrical current or voltage is applied to the film, these molecules or particles rearrange themselves, altering the propagation of light. This rearrangement can transition the film from transparent to opaque, or hold it at an intermediate level of transparency, depending on the strength and direction of the electrical current.

When the electrical current is no longer applied to the film, the molecules or particles revert to their original state, restoring the film to transparency. This reversible electrochromic process allows smart glass film to provide light control and privacy protection in various scenarios. This principle also makes smart glass film a highly practical material in applications ranging from architecture and automotive to aviation and beyond.
