Researchers have developed a new energy-saving paint that repels heat, comes in any color, and should last centuries.
Inspired by butterfly wings, this paint isn't made from pigment. Instead, color is created structurally through the arrangement of nanoparticles. The team is calling it 'plasmonic paint'.of plasmonic paint to cover a Boeing 747 – you'd need at least 454 kilograms of conventional commercial paint to do the same.
The electronic properties of each molecule control how much light is absorbed and, therefore, which color the paint appears. That means there needs to be a new pigment for every new paint color.
