Polymer dispersed liquid crystal film for variable-transparency glazing

The transmission of visible light and thermal energy through variable-transparency switchable glazing can be varied. Polymer-dispersed liquid crystal (PDLC) has been the most widely used variable-transparency glazing technology in the architectural and automotive industries due to its excellent optical performance, durability, and ease of processing into large-area products. Here we describe the electro-optical performance, temperature stability, and electrical and environmental durability of commercial PDLC products.
