International. Properly used thermochromic nano-coatings can help reduce energy use and generate savings. Coatings either absorb heat or allow it to be reflected, depending on their temperature.
Researchers at the Fraunhofer Institute demonstrated this phenomenon using samples of coated metal strips.
Nanoparticles possess an especially large surface area ratio from area to volume. This makes them extremely efficient and reactive. Small amounts are enough to produce large effects. Researchers are using this feature to create new coatings. They are incorporating active nano-materials into polymeric systems. These coatings can be easily applied as paint or varnish.
The process is highly adaptable and suitable for the processing of very varied nano-materials. An additional advantage is that small amounts of substances can be bonded in ecological, water-based plastic systems that emit almost no VOCs.
These coatings can be applied directly without first requesting a layer of primer – experts refer to this property as "direct-to-metal." In addition, the layers prevent oxygen from reaching the metal and therefore protect against corrosion.
