Conducting nano films based on multi-walled carbon nanotubes and poly(3,4-ethylene dioxy thiophene-poly(styrene sulfonate) for organic light-emitting diode

Tóm tắt

It is well known that multi-walled carbon nanotubes (MWCNTs) are an excellent nanomaterial. In this paper, the nanocomposite ultra-thin films were fabricated consisting of MWCNTs and poly (3,4-ethylene dioxy thiophene-poly(styrene sulfonate) (PEDOT-PSS) for organic light-emitting diode (OLED). The field-emission scanning electron microscopy (FESEM) images of MWCNTs thin films show that the diameter of MWCNTs are 10–30 nm and their length is 300–500 nm. Electrical and optical properties of the films are investigated and the sheet resistance can reach minimum value at 36.5 Ω sq−1 and the transparency of the film is about 80%. The current density–voltage (J–V) characteristics of the devices were also studied.
