Nano-Enabled Titanium Dioxide Ultraviolet Protective Layers for Cool-Color Roofing Research Project
The Department of Energy (DOE) is currently undertaking research into nano-enabled titanium dioxide (TiO2) ultraviolet (UV) protective layers for cool-color roofing applications.
This project entails optimizing and scaling up silicon dioxide-coated TiO2 nanocrystal synthesis and functionalization in aqueous solution in order to formulate a 10 gallon waterborne clear UV protective nanocomposite coating material.
This project is being undertaken between DOE and Nanotrons, a Massachusetts-based company that uses nano-engineering technologies to develop solutions to various energy issues.
The goals of this project are to scale up nanocrystal synthesis and functionalization in an aqueous solution, conduct UV testing of the material, optimize a nanocomposite film and spray coating process, and establish environmental requirements in order to complete a market analysis and offer this new technology to building owners. This material will eventually be a commercially-viable UV protective paint formulation for cool roofs, saving energy and money for building owners.
