Smart Windows

Development of enhanced PDLC smart glass with improved durability and performance for architectural and automotive applications.


Various types of devices have been developed over the last 50 years and applied to optical media such as glass to create so-called “smart glass” or “smart windows”. These devices include SPD (Suspended Particle Device), EC (Electro-chromic) and PDLC. The technologies enable automatic control of optical properties of glass, such as light transmission and visibility, and are applicable to varying types of glazing and represent a substantial increase in market potential for the glass industry. Uptake of these technologies is increasing, but a technological gap still exists with respect to withstanding environmental factors, which limits the application of technologies. The collaborators, CSIRO, Monash, QUT and iGlass undertook to solve these problems and become first to market with advanced PDLC devices suited as external windows for the Architectural and Automotive Industries.

The project ultimately has not been successful in providing a commercially viable product. Based on successful lab-scale experiments we believe this could be achieved within 12 months given appropriate additional support. The project has achieved a Smart Window device with excellent on-state transmission (as low as 2% on-state haze) and high privacy (>95% off-state haze). We have also developed new potentially patentable technology providing for very low off-axis haze. Lab-scale experiments point to the durability required for exterior transport or exterior architectural applications.
