Co-dispersion of Switchable Plasmonic Nanoparticles for Renewable Energy (e.g. smart windows) and Electro-Optic Applications


Functionalized nanomaterials combined with state-of-the-art liquid crystal selectively filter out light spectra. Such composites can be used in a variety of applications, such as more efficient and cost effective smart glass. Smart windows are currently in the prototype stage development at CU and suffer negligible loss of transparency while blocking 95% of infrared light in the summer. This process is almost completely reversible to reduce heating costs in winter. Furthermore, the user-controlled features will offer many additional options, such as dimming, privacy and color changing modes. An adhesive film version of this technology is contemplated to reduce the cost of retrofitting. These composites can also be used to create more energy efficient electronic displays.
