Discover the Future of Coatings: Plasmonic Paint – Lightweight, Energy Efficient, and Heat-Reflective
In a groundbreaking development, a researcher at the University of Central Florida (UCF) has pioneered a new method for producing coloured paint that is environmentally friendly, lightweight, and sustainable. By drawing inspiration from the vibrant colours found in nature, the researcher has created a plasmonic paint that replaces traditional pigment-based colorants with nanoscale structural arrangements of aluminum and aluminum oxide. This innovative approach not only offers a wide range of colours but also contributes to energy-saving efforts and has the potential to reduce global warming.
The colours are produced through the geometrical arrangement of colorless materials, resulting in stunning and long-lasting hues.
The plasmonic paint combines the structural colour flakes with a commercial binder, resulting in durable and vibrant paints of various colours. Unlike pigment-based colours that require artificial molecules, plasmonic paint utilizes only metals and oxides, making it more environmentally friendly. Moreover, this paint’s structural colouration reflects the entire infrared spectrum, leading to reduced heat absorption compared to standard commercial paint.
By significantly reducing the weight of vehicles and aircraft, this innovative coating promises improved fuel efficiency, lower operational costs, and reduced environmental impact.
Solar panels coated with plasmonic paint can reflect more sunlight and absorb less heat, resulting in increased energy production.
