Scientists have learned how to make OLED displays from human hair. Next in line - animal hair

A team of researchers from Queensland University of Technology has learned to use

human hair to create OLED displays.

How it works

Cut hair is cleaned of excess impurities andburn at a temperature of 240 degrees. The resulting carbon, hydrogen, and nitrogen are converted into carbon nanodots less than 10 nanometers in size. After that, they are applied to the polymer in small “islands”. The result is organic elements that are the active layer for OLED panels.

When applying to the working layer of small powerThe power of the nanoisland begins to emit blue or blue light. Blue light is obtained when a very small voltage is applied. As a result, information is displayed when saving energy. Brightness can reach 350 cd / m2, and on a solid glass substrate, a brightness of 700 cd / m2 can be achieved.

Of course, it is unlikely that it will be possible to establish the production of such OLED displays for smartphones and TVs, but they are perfect for wearable devices, small panels, packaging and medicines.

"Organic light-emitting devices onBased on carbon dots from human hair can be used for intelligent packaging. They can also be used where a small light source is required, for example, in signboards, smart dressings and medical devices, since the material itself is not toxic, ”the researchers note.

Now the next step is the development of OLED from animal hair.
