The aim of the project is to develop a novel electro-optical coating that bases on an unprecedented operational principle: switching between the disordered and aligned positioning of nanowires (nanotubes) relative to the incident light. The new concept represents a suspension of nanowires in a transparent matrix, applied as a thin film to a glass surface. The electro-optical effect of this material is provided by the variable shielding of the passing light by nanowires relative to their orientation, and by the unique optical properties of nanowires. The choice of the composition and dimensions of nanowires makes it possible to target specific regions of the spectrum, including the IR region. This means that the novel concept proposes a promising alternative to the only tunable IR shielding technology for windows there currently is – the electrochromic coatings . The principle of the new technology is much simpler than that of the electrochromic coatings, thus making it a likely candidate for bringing the tunable energy efficient windows to the everyday use. Furthermore, besides the cost-effectiveness the new coating does not suffer from the drawbacks that still harass the electrochromic coatings, like gradual loss of effect and relatively short lifetime. This project will have two major objectives: 1) synthesis of suitable nanowires, and 2) fabrication of the electro-optical coating; the latter will involve a profound supportive theoretical work. Also, there will be an important sub-objective of the project: developing methods for fabrication of transparent electrodes. This is necessary for the convenience of the technological production of the electro-optical glass, potentially making the integration of the electro-optical coating in between electrodes much easier than it would be by using commercial means (i.e. ITO-glass).
