Smart windows are becoming a key focus in the push for energy-efficient buildings and sustainable architecture. These windows can dynamically adjust their properties to control light and heat, improving comfort while reducing energy costs.
While traditional smart window technologies have been effective in managing either heat or light, they have limitations in simultaneously controlling both visible light and infrared (IR) radiation. New research introduces an innovative solution that promises to overcome these challenges, creating a more efficient and versatile smart window system.
In a recent study published in the Journal of Photonics for Energy, scientists demonstrated a novel approach combining liquid crystals (LCs) and nanoporous microparticles (NMPs) to create a smart window technology capable of controlling both visible light and infrared radiation. The key innovation involves adding a small concentration of NMPs to nematic LCs, resulting in a thin device that can rapidly change its transparency.
