Audi Creates Groundbreaking Color-Changing Paint Technology

Color-converting paints are quite popular in the aftermarket automotive sector, and manufacturers sporadically provide them as well. Nissan, for instance, offers Midnight Purple and Millennium Jade for the GT-R. Depending on how light reflects off them, different paint finishes have varied appearances. Another type of special paint changes color when heated, but in order to witness this change, you must spray the automobile with hot or cold water. There isn't much of a point to the effect, regardless of how it is produced, except from its obvious coolness and visual appeal. But are you really going to cover every square inch of your car with hot or cold water for an even effect?

Now, that would be different if you could instantly alter the color of your car. Better. something that I could choose. According to patents submitted to the German Patent Office, Audi intends to achieve just that. Audi intends to produce cleaner vehicles than ever before with an eye on the environment by switching to electric vehicles in the future, much like almost every other automaker. Any effort to cut energy use would contribute to achieving that objective. One of the ways they intend to do this is using the groundbreaking adaptive color technology developed by Audi.

According to studies, white vehicles use 1-2% less energy in the middle of summer than black ones. Audi plans to employ a display film that has a graphic film layer with a displayable image and a background color in order to reduce this usage. In other words, a color coat layer and a switchable film layer. The film layer alternates between two states: transparent and black. When this layer of film is activated, either A the displayable graphic is exhibited on the display film's top side in contrast to the background color, or B simply the background color is displayed. Similar efforts have been made by Rolls-Royce and BMW with the Privacy Suite feature in the Phantom.

Using polymer-dispersed liquid crystal particles (PDLC) based on a polymer liquid crystal film is one technique to make this work. The liquid crystal molecules rearrange themselves in the electrical field when an electrical voltage is applied, turning the previously opaque film transparent to the eye. This electrical voltage is regulated from inside the cabin. Simply turn off the electrical charge to make your automobile dark again, and the molecules will rearrange to create an opaque finish! The car would be more energy-efficient because less energy would be used for cooling. Please be aware that this might be incredibly expensive and might never be mass produced. But if it ever happens, electric cars like the Audi e-tron GT might be made more effective – and fashionable — just by pressing a button!
