Polymer Dispersed Liquid Crystals

Polymer Dispersed Liquid Crystals (PDLCs) are materials composed of tiny liquid crystal droplets embedded within a flexible polymer matrix. When no electric current is applied, the liquid crystals are randomly oriented, causing the material to appear cloudy or opaque by scattering light. When an electric current is applied, the liquid crystals align uniformly, making the material transparent. This switchable transparency is used in devices like smart windows, privacy screens, and displays, allowing users to control light transmission dynamically. PDLCs combine the optical properties of liquid crystals with the durability of polymers, making them versatile for various applications.
