Previously it was thought that the polymers do not conduct electricity and can only be insulators. But in the 70s opened the conductive organic compounds, which marked the beginning of an organic or “plastic” electronics. Electronic devices organically bend, cheaper devices based on silicon and weigh less. On the basis of polymers can be made flexible and transparent displays or cheap solar panels. But organic electronics yields silicon in durability and performance.
In order to use polymers in electronics, it is necessary to increase their conductivity, and scientists have found a “dopant” that is a dopant which increases it. -radial Carbonaceous material is most suitable for energy unoccupied molecular orbital of lowest energy – electrons are relatively easy to come off it, are free charges and increase the conductivity of the material.
Radialenom Experiments have shown that the fine material is mixed with polymers and increases their electrical conductivity in the hundreds.
“The fact that the dopant is well mixed with the polymer, allows you to create new classes of solar cells and organic field effect transistors, – said co-author Dmitry Ivanov studies. – I think it will give a significant boost to the development of electronic devices based on organic-based. ”
The results of their work, scientists have published in the journal Advanced Materials
