What is Smart Glass?
Smart glass, also known as switchable glass, is a type of glass whose light transmission properties are altered when voltage, light, or heat is applied. Typically, the glass changes from transparent to opaque, thereby blocking certain wavelengths of light. This technology is gaining popularity in architecture, automotive, and consumer electronics industries.
How Does Nanotechnology Enhance Smart Glass?
Nanotechnology plays a crucial role in the development of smart glass. By integrating
nanoparticles and
nanostructures into the glass, researchers can achieve precise control over its optical properties. This results in improved performance, such as faster switching speeds, greater control over transparency levels, and enhanced durability.
