Abstract

The main advantages of polymer LEDs, including easy manufacturing, low cost, flexibility, and transparency of resulting products, these parts have a special place in the world today. The purpose of this research is to design and manufacture polymer LEDs in the field of visible light based on conductive nano-polymer. In this research, a polypyrrole/carbon nanotube nanocomposite was prepared and its structural characteristics were examined by scanning electron microscope. The results of this evaluation showed that carbon nanotubes are attached to the surface of polypyrrole nanotubes and have good dispersion and uniformity on the surface of the substrate. Continuing with this nanocomposite, polyvinyl carbazole (PVK) was combined to create a doped LED polymer, especially for its illuminant component. Characterization was evaluated using the energy diagram and the current-voltage diagram of the fabricated diode, and compared with the LED fabricated by pure polyvinyl carbazole. The results showed that more current was obtained by using polypyrrole/carbon nanotube nanocomposite to the extent that at a constant voltage of 6 V, the current intensity was about 15 times. Converting the invisible light of LEDs into visible light by creating nanostructures was one of the achievements of the present research.
