Lightweight and Colorful Paint Made with Colorless Nanoparticles.

Researchers from the University of Central Florida have developed "plasmonic paint," a lightweight, eco-friendly material that has the potential to replace most colored coatings. The paint is composed of two colorless materials: aluminum nanoparticles and aluminum oxide nanostructures, which can manipulate visible light and create any color, giving rise to the world's first full-color structural paint. The plasmonic paint is more durable than standard paint and can reduce the overall weight of objects, which is critically beneficial for the aerospace industry.
