The Centre for Nano and Soft Matter Science in Bengaluru has made a significant contribution to smart window technology. A new approach involving hierarchical double network polymers combined with liquid crystals has been introduced, promising to take this modern feature to the next level.
Understanding Hierarchical Double Networks of Polymers
Hierarchical Double Networks (HDNs) of polymers, a type of Interpenetrating Polymer Networks (IPNs), are soft matter systems designed to combine different polymer networks optimizing various properties. These unique elements find their applications in areas such as smart windows and sensors. HDNs blend rigid and soft networks aiming to achieve optimal thermal, electrical, and optical properties, which can be tailored to meet specific requirements, including mechanical, optical, and electrical properties. Furthermore, polymers, the base for these HDNs, are large molecules composed of smaller chains of monomers. Common materials like plastic and rubber are typical examples of polymers.
Illuminating Advancements in Smart Windows
Smart windows have taken a leap forward with the integration of double networks. These networks incorporate different materials, enabling precise manipulation of properties and integrating multiple functionalities within a single window system.
Mastering Light and Temperature for Enhanced Control
The Bengaluru-based research team uses both light and temperature controls to develop double networks. The application of light helps form a self-assembled polymer network, while changes in temperature initiate the development of the second network that encapsulates the first one. This unique dual-stimuli approach offers unprecedented control over the properties of smart windows.
Trapping Liquid Crystals for Regulated Light Transmission
Liquid crystals, which play a key role in managing light transmission, are effectively trapped within the double network structure. This feature allows the smart windows to alternate between transparency and opacity, thereby offering privacy and contributing to energy conservation.
Fostering Energy Efficiency and Privacy Control
The innovative smart windows technology brings some notable benefits such as energy efficiency – as they consume minimal energy, these windows are both environmentally friendly and cost-effective. In terms of privacy control, smart windows offer the ability to switch from transparent to opaque, giving users control over their privacy. The windows are also capable of toggling between high and low haze states.
High-Resolution Windows for a Clear View
The modern techniques utilized in the production of smart windows allow for precise control over the level of opacity, ensuring excellent resolution. This improved visual quality is another critical factor that sets these new-age windows apart in the market.
