What is Smart Glass Technology?
Smart glass technology, also known as switchable glass, is a type of glass that can change its light transmission properties when voltage, light, or heat is applied. This allows it to transition between being transparent, translucent, or opaque, providing dynamic control over natural light and privacy.
How Does Nanotechnology Enhance Smart Glass?
Nanotechnology plays a crucial role in enhancing smart glass technology. By incorporating
nanoparticles or nanocoatings, the performance of smart glass can be significantly improved. These nanoscale materials can provide better control over light transmission, improve energy efficiency, and offer enhanced durability.
